They couldn't be any more different from one another, and their lives should never have crossed paths. Phil is a former pop star of the nineties, a one-hit wonder. Now, he works as a DJ, envies the famous Russian singer Oleg Gazmanov, and shies away from any kind of responsibility. Peter is a doctor, a dry-as-dust, pedantic careerist. He commits his daily agenda to a voice recorder, is terrified of asking a girl out on a date, and has never even heard of Gazmanov.
After Peter delivers the electric shock which restarts Phil's heart, they develop a vicarious connection, sharing each other's feelings and sensations. When one of them is hurt, the other winces in pain; when one is scared, the other feels frightened too. If one laughs, the other bursts into uncontrollable laughter. Phil's fun-filled life fraught with rollercoaster emotions soon turns Peter's systematic, measured existence upside down. But a more serious problem arises when, soon after Peter, Phil also falls in love with Peter's girlfriend.
