Paris, 1910. Panic sweeps the city as floodwaters rise and a monster is on the loose! Meanwhile a wacky inventor, his camera-crazy best friend, and a madcap monkey are on a mission to protect the monster, who has a rare and special talent. With the help of the beautiful but feisty singer Lucille, the team harbors the monster to keep him from the ghastly wannabe Mayor, Commissioner Maynott.
