Someone wants DCI Allison dead.

The Chameleon is the hitman hired for the job and he is on the move. DCI Allison and Sergeant Stringer are frustrated when they arrest the wrong man. The Chameleon is a master of disguise with numerous identities at his disposal. Only two people are able to identify him, Chrissy Stephens and police psychic Holly.

Chrissy is enrolled in a witness protection program, but will that save her? Holly has to take her chances.

DCI Allison is desperate to track down the elusive hitman who owns a white cat, but is forced into hiding as other coppers are dying and taking the hit.

Young Ronnie Soper, who has turned his life around, is the newest member on the force and goes undercover at a young offenders’ prison to root out the bullies and put a stop to the escalating suicides.

Meanwhile, Sergeant Stringer uncovers the real power behind the "hostess club" Kelly’s Wine Bar, when he seeks solace after the ruin of his marriage. The crime boss, Billy Boyle, appears to be the one responsible for the missing girls.

These threads begin to weave together, forming another complex series of cases for DCI Allison and his team. The question remains: will Allison die or will the Chameleon be caught?
