Anita Rani begins hosting a new programme this evening which sees people attempt to locate heroes who helped them out while they were caught up in the biggest events in living memory.
In the first episode of Saved By a Stranger, we meet a trainee clinical psychologist who was on a train targeted in the 7/7 bombings looking for the woman who comforted him through the ordeal.

Dragons' Den and Britain's Brightest Celebrity Family are also among the weekly returning programmes.
