Thrilling sequel finds down-and-out L.A. cop Nicholas "Big Nick" O'Brien (Gerard Butler) heading to Europe in pursuit of the architect behind the first film's heist-master jewel thief Donnie Wilson (O'Shea Jackson, Jr.). But with Wilson and the Panther mafia about to pull a job at the World Diamond Center, does O'Brien want to put the cuffs on his quarry, or does he want to join him?
