When 17-year-old Mark Rimsky moves across the country from North Carolina to California with fellow band mates Alex and Brandon, hoping to make it big in the music industry, the trio find more than they were expecting, waiting for them in their rented home. The previous resident, an A-list cheerleader from the local high school named Sarah, still haunts the home after being murdered in the downstairs kitchen. Sarah tries to scare the guys out, but eventually enters into an uneasy agreement with Mark and his friends to help her track down her killer.
Crazy circumstances and comical events that shape the gang's quest for justice push Sarah and Mark closer together, sparking a hilarious and lighthearted romance between the two; even though they both know they belong to different realities. All the while, pressure mounts for Mark to write an inspired song, with the band's record label threatening to drop them and end their dream of making it big.
