Standalone supernatural drama in two hour-long episodes for BBC1. Stars Joanne Whalley , Ray Stevenson, and Jemima Rooper.

When an international high-flyer and eligible bachelor takes some time out to rethink his life’s goals, a glimpse of an old flame on the streets of London prompts him to try her name in an internet search engine. One tantalising hint of her whereabouts is enough to send him looking, and what he tries to call mere curiosity begins to feel like the drive of destiny when, within twenty-four hours of their ‘chance’ encounter, both are convinced that their future lies together. She breaks up with her long-time partner and runs back to meet him. She never even sees the vehicle that kills her.

He goes into a downward spiral. Drinks, sleeps in his half-finished flat, finds himself an easy target for street people. In this susceptible state, he finds himself haunted by her elusive presence. When he finds himself at rock bottom, he calls Life Line.
