Detective Inspector Ron Scott of K Division, Greenock, Police Scotland, and his team are investigating a series of murders committed by a killer they are calling 'The Gardener.'

Curiously, the victims have been murdered by a perpetrator who uses common garden tools as his weapons of choice. In addition, a four-year-old girl has been brazenly abducted from a shopping mall by a man, in full sight of security cameras.

Greenock police have a lot on their hands, and time is of the essence.
