15 Storeys High (2002)

S7E11 Kidnap

Crime lord Metzger realizes that the IMF is behind the Aquarius Casino heist from the previous season and kidnaps Jim while he and Barney are on vacation. To secure evidence against him stored in a safe deposit box, he coerces the IMF into doing his bidding. The evidence, a letter, is being leveraged by Metzger's former associate, Connally, in exchange for Federal immunity in his testimony. Casey and Willy successfully swipe both keys and retrieve the letter, but Metzger’s henchman, Hawks, steals it to use as blackmail. In response, Barney concocts a forged letter, which leads the IMF to Jim and ultimately allows them to apprehend everyone involved.
