Andy Stitzer (Steve Carell) has a pleasant life with a nice apartment and a job stamping invoices at an electronics store. But at age 40, there's one thing Andy hasn't done, and it's really bothering his sex-obsessed male co-workers: Andy is still a virgin. Determined to help Andy get laid, the guys make it their mission to de-virginize him. But it all seems hopeless until Andy meets small business owner Trish (Catherine Keener), a single mom.
