After celebrating moving in with Juliet (Maggie Lawson) with their friends and family Shawn (James Roday) goes a bit overboard in his attempts to force Henry (Corbin Bernsen) into a friendship with Juliet’s stepfather Lloyd (Jeffrey Tambor). A simple package pick-up escalates quickly and gets his father shot at (twice). Henry’s ever-lessening trust in Lloyd isn’t improved by an impromptu plane ride into Mexico, being thrown into a Mexican jail, and being kidnapped by the most wanted man in Mexico (Tony Plana).
Shawn, Gus (Dulé Hill), and Juliet track their fathers to Mexico and to a Mexican police detective (Alex Quijano) who misreads the entire situation believing Lloyd and Henry were trying to return the Mexican gangster’s missing counterfeit engraving plates. However, a rash action by Lloyd recovers the plates (which were in the gangster’s possession all along), nearly gets all five of the Americans killed and buried in shallow graves, and, thanks to the actions of “Mexican Lassie,” puts the gangster and his stooges behind bars for good. Sadly for Frank, “Mexican Lassie” is a tad bit more corrupt than the American original.
Shawn’s quick thinking, and Juliet’s step-father’s knack for getting himself both into and out of tight fixes, saves Lloyd from his second attempt at digging his own grave in Mexico. And, despite it all, Shawn gets his wish as Henry and Lloyd somehow actually become friends due to their bizarre adventure together. The episode’s B-story involves Gus over-thinking and panicking about his relationship with Rachael (Parminder Nagra) after discovering she has a son. Although it provides some funny flip-flopping Gus moments, it doesn’t work as well as Tambor (who is a natural fit as the charming, but nearly always lying Lloyd) and Bernsen’s far more interesting story.
