Prison Officer Joan lives with her cantankerous mother, has a dormant love life and low self-esteem. Her colleague and best friend Trevor is a middle aged man whose face would best be described as 'lived in' - he hasn't had a leg over in years.
Katrina and Cath share a cell at Maple Prison. When Cath's handsome brother Patrick comes to visit, Joan is instantly smitten and the cons hatch a plan to use him to get favours from the screw.
Joan thinks she's in love although Trevor and her mother, Mable, are sceptical. Patrick's secret business venture seems to be going well with Joan's help but how long will it be before he tires of Joan and why is it only Mable that can see through his smile?
Desperation and greed dominate Karen Woods' prison drama.
