Aaron Roach Bridgeman is presenting a special one off documentary for Channel 5 exploring the devastating effects of how one punch can change so many lives.

Violence is a major problem on Britain’s streets, but what happens when a single punch takes a life? Aaron documents a number of sobering cases in which one punch, thrown in the midst of a drunken argument, unprovoked, or in self-defense, has killed. He speaks to the families of the victims, and those who have been convicted.
