Too expensive for a "quota quickie" but not quite costly enough to qualify as an "A" picture, Happy is a shapeless but generally satisfying vehicle for several of England's top music-hall attractions. Stanley Lupino (Ida's dad) and Laddie Cliff star as Frank and George, a pair of nightclub musicians living in an attic owned by irascible Scotsman Simmy (Will Fyffe). Hoping to get rich quick, Frank invents a device that, when attached to an automobile, will immediately alert the police if the car is stolen. A millionaire car manufacturer is interested in the device, but agrees to purchase it only after his pretty daughter falls in love with Frank. Balking at the idea of marrying the girl for her money and influence, Frank nearly throws away his chance for true happiness, but it's all smiles and happy songs at the end.
