Like a cross between CSI: CRIME SCENE INVESTIGATION and Darren Aronofsky's indie feature PI, NUMB3RS blends crime-drama with mathematics for a smart and creepy spin on the police-detective genre. Executive produced by Ridley Scott (ALIEN) and Tony Scott (TRUE ROMANCE), the series centres on a pragmatically minded FBI agent, Don Eppes (NORTHERN EXPOSURE's Rob Morrow), who invites his math-genius younger brother, Charlie (David Krumholz), to help him solve challenging cases using mathematical theories based on equations and probability. Dark and moody with a near-cinematic feel, NUMB3RS has won both fans and acclaim for its innovative approach to the conventional crime-drama formula. This collection presents the show's fourth series in its entirety.
