Sam believes his life is finally starting to make sense as he excitedly plans to live with his dad Peter (Richard Coyle) as soon as he’s released from prison.

First he must accompany his mum Jenny to a funeral, where his inappropriate behaviour prompts Chrissy’s dad Bill (Daniel Mays) to give him a good talking-to, while Jenny, who would hate to see history repeating itself, tries to warn Chrissy off her son.

But when the young couple run off to meet Peter, how will Sam’s unpredictable father react to Chrissy? And what does Peter really want with Sam?

A thrilling conclusion to a compelling series, which has made a star out of its lead, the fantastic Jack Rowan.
