Never a Dull Moment

When practicing for a role, actor Jack is mistaken for the killer Ace. He doesn't realize this until it's too late and is carried off to gangster boss Leo Smooth, who wants Ace to do a job for him. Fearing for his life, Jack plays his role, but always searching for a way out of the well-guarded house.
