Based on the best-selling novels by Scottish crime writer Ian Rankin, Detective Inspector John Rebus (John Hannah) is a tough, street-smart sleuth based in Edinburgh with an uncanny genius for solving complicated crimes. Rebus investigates when an old friend, DI Jack Morton, is shot during an undercover operation at a pharmaceuticals factory which has become a hub for cocaine dealing and gun-running by a well-known mobster and his latest team of upstart thugs.
