A prison officer and a convicted killer must work together to solve a brutal murder and expose conspiracy inside a prison.

Ariadne Teddington is surrounded by people who lie but that is to be expected when you work in prison where every man claims to be innocent.

Charlie Bell, an ex Detective, now finds himself in that prison serving time for murder after having taken the law into his own hands.

When a fellow inmate is killed Charlie is asked to investigate the case from the inside. Soon Charlie finds himself working with Ariande but she is a guard, he is an inmate and some lines should never be crossed...

Can two people on different sides of the law come together to solve the case?

And do the answers lie closer to home than anyone ever imagined?
