Collision, from across the pond, was apparently a five-hour miniseries, cut to just over three for DVD. It stars Douglas Henshall, Lucy Griffiths, Kate Ashfield, Philip Davis, Sylvia Syms, Paul McGann, and Matt Ryan.
It's a sort of Bridge of San Luis Rey with vehicles. John Tolin (Henshall) is a police detective who has had some sadness in his life, though we're not sure what when the story begins. He has a wheelchair-bound daughter (Jo Woodcock) about to go to college and no wife. He agrees to investigate a multi-car collision on the A12 highway which killed three people. He and another investigator (Kate Ashfield) work together in spite of having been involved in a relationship that ended badly.
The investigation leads to more questions than it answers. Tolin delves into the lives of the people involved and finds corporate espionage, an unexplained death, smuggling, and someone living under an alias; one person, driving an antiques van, has disappeared. After the accident, there is a murder and another death, and a married man seemingly falls for a younger woman he met as a direct result of the accident.
Low-key, compelling drama that will keep you guessing.
