Super (2010)

Frank Darrbo is a hapless fry cook. When his wife Sarah falls off the wagon and dumps him for Jacques, a drug dealer, Frank tries to get her back by reporting her kidnapped, grabbing her from Jacques' car, and wailing for her to return. After watching Christian TV and having a vision, he becomes a superhero to fight evil. He sews a costume, finds a weapon (a pipe wrench) and looks for crimes to stop. He has problems: his wrench inflicts real injury, so the cops want him for being a vigilante, his sense of boundaries is flawed, and Jacques' gang has guns. Libby, a clerk at a comic book store, becomes his sidekick, and it's time to go save Sarah. What chance do they have?
