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. A series of seemingly unconnected burglaries helps police to crack a county lines drug-dealing conspiracy. A single consumer complaint leads to police bringing down a national SMS fraud affecting thousands, and a cunning con-woman is discovered living a life of luxury with stolen money.
