To forget his past and start a new life, Marius, who is about to get out from the prison, takes his cellmate's identity and pretending as being him. But he is not know that he makes more troubles. After some time he knows that his cellmate is a gangster and he has a worse past.
In a twist on the "grandma con," he (Ribisi) turns up at the home of his cellmate's grandparents and claims to be long-lost Pete. The believing grandparents take him in, and I won't spoil the delightful results with details
Sneaky Pete is indeed pretty sneaky. At first you're rolling your eyes at what seems an absurd stretch of a premise, but soon enough you're buying its always-on-edge predicaments and after a few episodes you're hooked into its story-upon-story acrobatics.
