New York City. Melvin Udall, a cranky, bigoted, obsessive-compulsive writer, finds his life turned upside down when neighboring gay artist Simon is hospitalized and his dog is entrusted to Melvin. In addition, Carol, the only waitress who will tolerate him, must leave work to care for her sick son, making it impossible for Melvin to eat breakfast.
Mild-mannered Paul Blart (Kevin James) has always had huge dreams of becoming a State Trooper. Until then, he patrols the local mall as a security guard. With his closely cropped moustache, personal transporter and gung-ho attitude, only Blart seems to take his job seriously. All that changes when a team of thugs raids the mall and takes hostages. Untrained, unarmed and a super-size target, Blart has to become a real cop to save the day.
