As the search for Julie intensifies, Tom and Sam have to deal with an emotional Dani and a restless John - whose behaviour begins to arouse suspicion. Tom and Sam's worries about John are further increased when John sneaks away to meet a dodgy-looking acquaintance in a car park. When it becomes clear that Dani is also very wary of her would-be stepfather, Sam and Tom begin to fear that John is somehow involved in Julie's disappearance. Tom's former boss turns up and it is clear she wants to keep him away from the case, which causes Sam to wonder about the real reason he left the police force.
