The House Bunny

Shelley Darlingson, raised in an orphanage, finds a sense of belonging when she becomes a Playboy Mansion resident. However, she's unexpectedly expelled on her 27th birthday due to being too old. In desperation, she becomes the house mother for a sorority of misfits, whose house is at risk of being taken over by a rival group of mean girls unless they find 30 new pledges within a few months. Shelley tries to make the Zetas appealing by not being too intelligent, hosting great parties, and making the boys interested in their house.
