A traffic collision leads police to a cold-blooded killer. A casino gambler proves to be the key to a money-laundering scheme, and a speeding motorbike leads police to a prolific burglar.

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

An everyday burglary proves to hold the solution to a series of dramatic ram-raids. A report of a minor theft leads to a case of kidnapping and false imprisonment, and a spike in consumer complaints leads to the conviction of some prolific fraudsters.
