Rebecca (Marin Ireland) is a terminally unemployed actress rooming with an equally unsuccessful screenwriter, Sarfras (Aasif Mandvi). Much to the derision of her WASP family, comprising of senators (Amy Redford), judges (Peter McRobbie) and lawyers (Kerri Bishe), Rebecca ekes out a living by caring for a blind diabetic woman whilst careering from one disastrous relationship to the next. When invited to understudy the movie star, Simone, star of the "Drive By" trilogy, Harwin (Kelli Giddish), in Electra, Rebecca's unfulfillment is compounded: despite outshining the "Queen of action movies" with her talent, Rebecca finds herself bullied or ignored by the cast and crew, including Ian the neurotic director (Richard Kind) and Alison, the duplicitous stage manager (Marcia Debonis). Her salvation appears to be in a relationship with the seemingly perfect New York Firefighter, Bobby (Paul Sparks). As accidents start to befall the leading ladies of Electra and Rebecca's star begins to rise, suspicion surrounds the Understudy. Can Rebecca hold onto the leading role and her freedom?
