A group of lifelong mob movie extras mount a production of Shakespeare's Julius Caesar in their local Staten Island theater in order to finally get some speaking roles. But the theater is the secret hideout of a real-life gangster who fancies himself an actor, and whom the FBI are hunting for the recent murder of a Broadway producer. The Feds insert their own undercover agent to audition for the role of Cassius, seeking to determine who is the real gangster among a cast of make-believe criminals. All the while, the oblivious cast seek only to prove to themselves, their families, and friends that they are more than just extras.

Jung-sik and Dae-soo are twenty-year-old students. They haven't yet had their first time and all they talk about is sex. Since they are unable to seal the deal, they watch porn instead. One day, Min-jung, Jung-sik's mother's friend, moves in with them to stay until her divorce settles. She will make dreams come true.

The plot and setting is actually a bit like Keaton's The Three Ages will be in 1923. But less sophisticated: The Roman Emperor Mulius Caesar borrows more money than he should. The loan shark is all over him and exploits this to get near the emperor's daughter. A slave falls in love with the daughter and sends the loan shark in a rage – unless the slave is sent to Colosseum he will foreclose the emperor's mortgage.
