Documentary exploring the phenomenon of `crocodile tears', when individuals attempt to conceal their guilt by making emotional public appeals for information to solve the crimes for which they are responsible. The programme investigates the levels of deception and betrayal involved in a number of high-profile cases, illustrated by lawyer Milton Firman, who gives a first-hand account of how he was convinced by claims of innocence from two parents who were eventually charged with the murder of their daughter.
