What's Up, Doc? (1972)

A musicologist travels to San Francisco to vie for a prestigious research grant, but his orderly life is upended when a charming, free-spirited woman, who has a knack for creating chaos, sets her sights on him. Amidst this, a wealthy socialite's jewels are stolen, a government whistle-blower arrives with top-secret documents, and an array of identical overnight bags causes a whirlwind of misplaced items and mistaken identities.
