"Crunching Numb3rs: Trust Metric", consists of five featurettes: Pre-Production, The Tony Touch, The Ambush, The Freighter, and Post-Production.

The premise of the series Numb3rs revolves around FBI Agent Don Eppes (Rob Morrow, Northern Exposure) and his professor brother Charlie (David Krumholtz, The Santa Clause), who uses his mathemical skills to help his sibling and his team solve the most difficult cases. Being on Friday nights would have equal cancellation, right? Not when you have added the mega-success CBS has had with the franchise of CSI over the last several years into the equation. Remember, CSI started on Friday nights in its first season before moving to Thursday as the #1 show in America. ***

Still, Numb3rs continues to remain an favorite on Friday nights since its debut as a mid-season replacement in 2005. Season four consists of 18 strike-shortened episodes, starting with the aftermath of Don and his team discovering an traitor within them. Charlie decides to follow into his brother's footsteps and goes into training for the FBI, but may have second doubts at the end of the finale when he and Don clash on a case that challenges their personal beliefs. And speaking of the finale, one of the team members will be leaving the bureau for good. ***
