Elliot Vail is a floundering San Francisco stand-up comedian who will do anything for a cheap place to live. So when strange Edward Bockman offers him free rent in exchange for some odd dos and don'ts, Elliot thinks his luck is about to change. After all, despite Bockman's over-active imagination, head-to-toe Robin Hood costume and locked bedroom door, he seems nice enough.

Little does Elliot know that his new landlord is time-traveling to trysts with an ex-mistress of England's King Charles II...and that he'll soon be expected to rescue Bockman from a 17th-century prison and a deadly outbreak of the Black Plague.
