A drifter named Lorne Malvo arrives in small-town Minnesota and influences the population with his malice and violence, including put-upon insurance salesman Lester Nygaard.

Dolph Springer wakes up one morning to realize he has lost the love of his life, his dog, Paul. During his quest to get Paul (and his life) back, Dolph radically changes the lives of others: a pizza-delivering nymphomaniac, a jogging-addict neighbor in search of completeness, an opportunistic French-Mexican gardener, and an off-kilter pet detective. In his journey to find Paul, Dolph may lose something even more vital: his mind.

Paul Blart is a mild-mannered, dutiful family man who works as a security guard in a New Jersey mall. For years, he has applied to become a cop, but he always fails the physical exam because he is overweight. One day, a gang of organized criminals put the mall under siege and take hostages. Blart becomes trapped inside, and because of his sense of duty, refuses to leave. He thus becomes the police department's eyes on the inside and attempts to stop the criminals on his own.
