Alan and Tricia Hamilton (David Tennant and Sarah Parish) are very happy. He’s the head of a
building firm and on top of his game. She’s a part-time beautician and a full time mother to their two sons.
One day their perfect, if unremarkable, life is torn apart when a last minute decision to pop out for a
quick drink with a colleague sees Alan step out in front of a passing car.
The resulting accident leaves him in a deep coma but with remarkably few physical injuries.
Desperately worried about him, Tricia is delighted when he comes round – only to discover that the man she loved
has disappeared. His behaviour’s changed, he’s lost all of his inhibitions and he veers from angry and frustrated
to vulnerable and childlike. Simple tasks like making toast and getting dressed are beyond him, he’s unable to
hold down the job he loves and he plays and laughs with his sons as if he’s a teenager.
Alan’s behaviour puts his relationship with Tricia under intolerable pressure as she realises that
the husband she loves is in there somewhere – she just has to try and find him.
