Riffraff (2009)

At Chicago's North Avenue Beach, the lifeguards are the law. These ragtags will do everything in their power to make sure you don't go out past your waist. Best friends Hughie (the hopeless romantic) and Otis (the ladykiller) get caught in one love triangle after another as young vixen Maggie and tomboy May make it hard for them to keep their eyes on the water at all times. As the summer sun heats up, so does tension among the crew, and their despotic superiors make sure that's it's never just another day at the beach.
