Psychotic teenager Sam (Jack Rowan) is playing some downright dangerous games.
Not only is he testing his only school friend Oscar, but he’s also creepily hankering after attention from Oscar’s dad, Mike.
He’s an expert at faking grief after last week’s shock events, but is his mum Jenny (Romola Garai) convinced?
Jenny has enough going on, though, especially when Oscar’s mum Lauren warns her to keep Sam away from her son.
Plus, Peter’s parole hearing is coming up – can Jenny continue to hide the truth from Sam about his violent father?
This beautifully sinister drama continues to shock and scare, with Jack Rowan’s ability to switch from nice to nasty in a nanosecond unparalleled.
