Fussy neatnik Felix Unger (Jack Lemmon) and incorrigible slob Oscar Madison (Walter Matthau) haven't seen each other since they shared an apartment life three decades ago but they're reunited on a trip to the wedding of Oscar's son (Jonathan Silverman) and Felix's daughter (Lisa Waltz). A traumatic road trip full of misadventures ensues in this delightful tale about the classic mismatched characters.
