Sylvester Cat is a lighthouse keeper's mouse-catcher assigned to keep a mouse from unplugging the light. The mouse only wants a good night's sleep and asks Hippety Hopper, the baby kangaroo who has just crashed off of a ship on the nearby rocks, to help him fight Sylvester and keep the lighthouse light turned off.
