What is The Heights on Channel 5 about?

The Heights introduces working mum Ellen who is devoted to her children and fiercely protective of them. They are happily living in London when “cracks began to appear in their family life”.

But a devastating tragedy leaves her consumed by grief, rage and a growing obsession with the truth. Jumping between the past and present day, family secrets and lies unravel in this thrilling new series.”

Sebastian Cardwell, Deputy Chief Content Officer at Channel 5, said: “We’re thrilled to bring this adaption of Louise Candlish’s bestselling novel to UK screens. The Heights is a key part of Channel 5’s 2026 drama slate and we’re so pleased to have Anna Friel leading a stellar cast.”

Is The Heights on Channel 5 based on a book?

The Channel 5 series is an adaptation of the novel of the same name by Louise Candlish, the bestselling author of A Neighbour’s Guide to Murder. The author said: “I couldn’t be happier to see The Heights adapted for 5 by the brilliant team at Clapperboard. Anna Friel is one of the finest acting talents of our generation and for her to be headlining as Ellen is truly a thrill.”

The Heights is published by Simon & Schuster UK and by Atria Books in the US. It’s described as a “nail-biting story about a mother’s obsession with revenge”.

A synopsis for the book reads: “Ellen Saint is just your average mum. Devoted to her family, she’s no different from any other mother who wants the best for her kids. But when her teenage son Lucas brings a new friend home, cracks start to appear in Ellen’s perfect family life.

“Kieran Watts isn’t like Lucas. He’s rude, obnoxious and reckless. And Ellen can only watch in despair as her son falls deeper under his influence. Then Ellen’s whole world implodes and she embarks on an obsessive need to get revenge. There is nothing you won’t do for your children – even murder…”

The Guardian called the book “masterly plotted and compulsive”, while Sunday Express said: “Stylish and sinister, this is a dark tale with a punch to the ending.”

Mail on Sunday added: “A thoroughly compelling thriller that shows off Candlish’s trademark mix of smartly-observed London life, crafty twists and unreliable, but all-too-believable characters.”

Prentiss Fraser, President of FOX Entertainment Global, concludes: “The Heights is exactly the kind of premium, emotionally gripping storytelling that resonates with audiences around the world. With Louise Candlish’s compelling novel, and Anna Friel delivering a powerhouse lead performance, we’re proud to work with 5 on this exceptional series.”
