Episode 4

Big Little Crimes tells the remarkable stories of ordinary beat coppers who stumble upon a key piece of evidence - a haul of stolen goods, a suspect on the run - and bring a major criminal to justice.

A road traffic collision leads to the conviction of a cold-blooded killer. A glamorous casino patron turns out to be the key that lets police unlock an international money-laundering scheme, and a speeding motorbike leads police to arrest a prolific burglar.
