Numb3rs Episode 4.15 End Game

Clay Porter's father and sister are taken hostage by a gang of military thieves, forcing him to return from hiding in Mexico for the murders he allegedly committed in the US. Don's team uncovers the motive behind these kidnappings, revealing that the military thieves need Clay because they believe he knows the location of stolen money in Iraq. Since Clay is still wanted for the murders, he is immediately apprehended as soon as he arrives on US soil. After Don decides to cut him lose and use him as bait, he becomes wanted again when one of the thieves is found murdered. The thieves retaliate by killing Clay's father, forcing Clay to plead guilty to the original murders if Don helps him get his sister back. Charlie's math provides the thieves' location, and Clay is able to save his sister.
