It's a lovely summer day, and Mickey and Minnie Mouse want nothing more than to enjoy a nice, easy boat ride. But when they climb aboard a rowboat, a startled squirrel jumps into their boat, scaring Mickey and Minnie and causing them to topple into the water! They hop aboard Donald Duck's speedboat, but they get stranded in the water. Nothing seems to be going right! Can Mickey and Minnie manage to stay dry long enough to enjoy a nice, easy boat ride, or will their perfect summer day be ruined?
