Eyewitness

Ten people are secretly filmed as they witness what they believe to be a real crime - a knife attack in a Manchester pub. But when they are later interviewed by the police, their memories are radically different from each other's and from what really happened.

When bystanders get caught up in a botched armed robbery and one of them is kidnapped, what effect do weapons and fear have on their memories? The difference between recall and recognition is illustrated by witnesses who can't describe suspects they clearly saw, yet recognize suspects they can't describe.

Having many witnesses to a crime helps the police piece together the facts. But what happens when the only witness is also the victim? Stephanie Slater was blindfolded during her kidnap, but her attacker was caught because police interviewers were able to help her recall the sounds and smells she experienced during her ordeal.
