Roger Greenberg (Ben Stiller- Zoolander, Night At The Museum) is single, fortyish and deliberately doing nothing. In search of a place to restart his life, he agrees to house sit for his brother in LA and tries to reconnect with his former bandmate (Rhys Ifans- Notthing Hill) and ex-girlfriend (Jennifer Jason Leigh). But old friends aren't necessarily still best friends, and Greenberg soon finds himself forging a connection with his brother's personal assistant, Florence (Greta Gerwig). Despite his best attempts not to be drawn in, Greenberg comes to realise that he may at last have found a reason to be happy.
