To track down the infamous arms dealer Dan "Daniel" Valdano (guest star David Figlioli), Jake and Terry go undercover at an illegal gambling club, but when Holt gets involved to coach the two in the art of poker, his addiction resurfaces. Meanwhile, Boyle buys a food truck that was formerly used in a brutal string of murders without telling his investor, Amy, and Hitchcock and Scully challenge Rosa to a "Butt-lympics".
