That’s a Monday. 4 p.m. PT / 7 p.m. ET on Acorn TV.

The show premiered last year on Acorn. All six episodes dropped at once. That’s how Acorn does their originals. No weekly waiting. No cliffhangers between episodes.

If you missed it in 2026, it’s still there. Acorn doesn’t remove their originals. Everything stays.

Summerwater Season 1 cast

Here’s the full cast:

• Dougray Scott as David Campbell
• Valene Kane as Justine Tindall
• Anna Próchniak as Alina Piotrowska
• Colin MacDougall as The Official
• Daniel Rigby as Steve Tindall

• Shirley Henderson as Annie Campbell
• Silvie Furneaux as Becky
• Ingeborga Dapkunaite as Rasa Zaliskviciene
• James Harkness as Gavin Macquoid
• Emily Briscoe as Lola Tindall

Dougray Scott leads the cast. Mission: Impossible 2. Desperate Housewives. Batwoman. He plays David Campbell. A father trying to hold his family together. Not doing a great job.

Valene Kane plays Justine Tindall. The Fall. Rogue One. Her character is hiding something from her husband. The trailer hints at it. The show reveals it in Episode 2.

Anna Próchniak plays Alina Piotrowska. She was in Baptiste and The Forgotten. Her character is Polish. Working at the cabin park. She sees everything. She says nothing. Until she does.

Shirley Henderson plays Annie Campbell. Harry Potter fans know her as Moaning Myrtle. Trainspotting fans know her too. She plays the wife. The one who knows her marriage is over but won’t say it out loud.

Daniel Rigby plays Steve Tindall. Eric and Ernie. Lilting. He’s the husband who thinks everything is fine. Everything is not fine.

Shereen Cutkelvin plays Millie Nkene. She’s a singer. The Voice UK. This is her first acting role. She plays a mother trying to give her daughter a good holiday on a budget.

Ingeborga Dapkunaite plays Rasa Zaliskviciene. Lithuanian actress. She’s been in Seven Years in Tibet and War & Peace. Her character is Alina’s mother. They don’t get along.

James Harkness plays Gavin Macquoid. Limbo. The Victim. He plays the angry one. The one who complains about everything. The one you want to avoid at the cabin park.

Colin MacDougall plays The Official. That’s his actual character name. He shows up in Episode 4. He’s there to enforce rules. Nobody likes him.

Silvie Furneaux and Emily Briscoe play the younger generation. Becky and Lola. Teenagers. Bored. Looking for trouble. They find it.

What will Summerwater Season 1 be about?

Here’s the setup.

A loch-side cabin park in Scotland. Families in separate vacation homes. Each one dealing with their own mess. Hidden tensions. Personal struggles. Things they don’t talk about at home but can’t escape here.

The show follows multiple families over the course of a single weekend. Rainy. Cold. The kind of Scottish summer where you never take off your jacket.

• The Tindalls. Justine and Steve. Their daughter Lola. They’re here to save their marriage. It’s not working.
• The Campbells. David and Annie. They’ve been married for twenty-five years. They don’t talk anymore. They don’t fight either. That’s worse.
• Alina and Rasa. Mother and daughter. Polish immigrants. Working at the cabin park. Cleaning other people’s cabins. Living in a small one out back.
• The Hendersons. Millie and her daughter. Here for a cheap holiday. Millie works two jobs. She saved for months. She wants one good week.
• Gavin. The complainer. Here alone. Doesn’t talk to anyone. Just sits outside and smokes and glares.

The show is quiet. Slow. Not much happens in terms of plot. But everything happens in terms of emotion.

Brief moments of joy. A child laughing. A couple holding hands. A sunset through the rain. Then back to the tensions. Back to the things unsaid.

Episode 6 is called “The Fire.” Something burns. Not going to say what. But the whole season builds to that moment.

Is there a trailer for Summerwater Season 1?

Yes. Acorn released it back in May 2026.

One minute and thirty seconds. Shows the loch. The cabins. Rain on the water. Then quick cuts of each family. A fight. A kiss. A secret whispered. A door slamming.

The trailer doesn’t show the fire. That’s the hook. You know something bad happens. You don’t know what.

Acorn also released individual character trailers. Thirty seconds each. Focus on one family per trailer. The Tindalls. The Campbells. Alina and Rasa. Each one gives a little more context.

Search “Summerwater Acorn TV trailer” on YouTube. The main trailer has about 800,000 views. Not huge. Acorn shows have loyal audiences. Not blockbuster numbers.

No behind-the-scenes footage. Acorn doesn’t do that for their smaller shows. Budget thing.

What to Expect and When?

The show is already out. May 25, 2026. All six episodes. Still on Acorn right now.

If you haven’t watched it yet, here’s what to expect:

Episode 1: The Tindalls — Introduces Justine and Steve. Their marriage is in trouble. Lola knows. They think she doesn’t.

Episode 2: The Lovers — Not who you think. Two people from different families. A moment in the rain. A secret that can’t stay secret.

Episode 3: The Zaliskevicius-Piotrowskas — Alina and Rasa’s backstory. Why they left Poland. Why they don’t talk. Why Rasa drinks.

Episode 4: The Hendersons — Millie’s story. Single mother. Two jobs. This holiday is everything to her. And then something happens.

Episode 5: Annie — Focuses on Shirley Henderson’s character. The wife who knows. The longest episode. The saddest one.

Episode 6: The Fire — Everything comes together. Not everyone makes it out the same. No major deaths. But losses.

What not to expect:

• Action. This is not a thriller. It’s a slow burn character study.
• Answers to everything. Some things are left ambiguous. That’s the point.
• A second season. The show is based on a novel. The novel ends here.

When to watch Summerwater Season 1 on Acorn TV

Any time. It’s already there.

Acorn doesn’t do premiere windows. Once a show drops, it stays. You can watch it today. You can watch it next year. No rush.

If you want the “appointment viewing” experience, May 25, 2026 was the day. But that’s passed. Just watch it whenever.

New episodes: There are no new episodes. Season 1 is complete. Six episodes. Done.

Season 2: Not confirmed. The novel doesn’t have a sequel. But Acorn could adapt something else. Nothing announced.

Summerwater Season 1 premiere date prediction

No prediction needed. The show already premiered. May 25, 2026.

If you’re asking about a potential Season 2, that’s different. Acorn hasn’t announced anything. The novel doesn’t have a sequel. The showrunner said in an interview that they told the complete story.

So don’t hold your breath for Season 2. This is a one-season thing. Limited series. That’s fine. Not everything needs to be an ongoing franchise.

Summerwater Season 1 filming locations

Balfron, Stirling, Scotland. That’s the short answer.

The show filmed entirely in Scotland. Loch Lomond area. About an hour north of Glasgow.

Specific locations:

• Loch Lomond — Used for all the loch shots. The water. The islands. The mountains in the background. It’s one of Scotland’s most famous lochs. Looks gorgeous on screen.
• Balfron — A small village. Used for the cabin park exterior. The production built the cabins from scratch. Then took them down after filming. Nothing permanent.
• Stirling — Used for the town scenes. When characters leave the cabin park to buy supplies. That’s Stirling. The castle is visible in one shot.
• Soundstage in Glasgow — Used for interior scenes. The cabins are real exteriors but the inside shots are on a soundstage. Controlled environment. Easier for lighting.

No filming outside Scotland. The whole show stays in one location. That’s the point. These families are trapped together. Can’t leave. Can’t escape.

If you want to visit the locations:

• Loch Lomond is a public loch. Go anytime. Drive the A82. Stop at the viewpoints. Bring a raincoat.
• Balfron is a real village. The cabin park location is an empty field now. Nothing to see.
• Stirling is a real city. Visit the castle. Walk the old town. Good pubs.
• The Glasgow soundstage is not open to the public.

Weather during filming: Scottish summer. Which means rain. Cold rain. Wind. The actors wore coats in every exterior scene. That’s not wardrobe. That’s necessity.
