'Wattsy' Wirth is fresh out of prison and determined to go straight. But like his ex cell-mate, Johnny Spit, and reformed gangster Dabba Barrington, he discovers that getting on the straight and narrow is a lot harder than he thought. On the outside there are old scores and old enemies, as well as a few new ones, like the newly formed Crimes Investigation Commission. With the CIC breathing down their necks and pressure from underworld boss Chicka Martin and corrupt cop Arnie Deviers, it will take Wattsy, Spit and Dabba all their street smarts and rat cunning to stay one step ahead and become square-heads.
