For Josh Harper, being in show-business means everything he ever wanted - money, fame, a beautiful wife, a lead role on the London stage.
For Stephen C. McQueen, on the other hand, it means a disastrous career playing passers-by and dead people. He`s stuck with an unfortunate name, a hopeless agent, a daughter he barely knows, and a job as understudy to Josh Harper, the 12th Sexiest Man in the World.
And things get even more difficult when Stephen falls in love with Josh`s clever, funny wife Nora. But might there yet be a way for Stephen to get his Big Break?
THE UNDERSTUDY is a scintillating comedy of ambition, celebrity, jealousy and love.
