A young, hipster entrepreneur (Nick Kroll) crashes and burns on the eve of his company's big launch. With his entire life in disarray, he leaves Manhattan to move in with his estranged pregnant sister (Rose Byrne), brother-in-law (Bobby Cannavale) and three year-old nephew in the suburbs - only to become their nanny. Faced with real responsibility, he may finally have to grow up - but not without some bad behavior first.
