Capt. Jack Wander (FOREST WHITAKER) and his squad of L.A. cops -- Det. Tom Ludlow (KEANU REEVES), Sgt. Mike Clady (JAY MOHR), Det. Cosmo Santos (AMAURY NOLASCO) and Det. Dante Demille (JOHN CORBETT) -- are a close-knit team that might not always get along, but they always cover each other's backs.
That's especially needed for Tom who's still bitter and hurting over his cheating wife's death and thus takes out his anger and frustration on most every low-life he encounters. His latest illegal activity has left four perps dead, but also freed two kidnapped girls, thus earning Jack a promotion, and Tom the concerned attention of emergency room nurse Grace Garcia (MARTHA HIGAREDA), not to mention his boss' ever-growing gratitude.
That comes in handy when Capt. James Biggs (HUGH LAURIE) from Internal Affairs comes snooping around, and especially when Tom learns that his own ex-partner, Det. Terrence Washington (TERRY CREWS), is reportedly working with Biggs to get the rogue cop off the streets.
Befitting his usual operating procedure, Tom goes to have it out with Washington, but just as he does, two masked thugs shoot his former partner dead. Jack has Tom take the convenience store's security tape to cover his man, but its disappearance only raises Biggs' suspicions.
Sensing he's going to be framed for the murder -- and feeling responsible for bringing justice to the dead man's wife, Linda (NAOMIE HARRIS) -- Tom teams with forensics detective Paul Diskant (CHRIS EVANS) and uses the likes of flashy criminal Scribble (CEDRIC THE ENTERTAINER) to try to find out who's responsible and then deliver his own brand of justice.
