A space shuttle mission investigating Halley's Comet brings back a malevolent race of space vampires who transform most of London's population into zombies. The only survivor of the expedition and British authorities attempt to capture a mysterious but beautiful alien woman who appears responsible.
Orlando is forced to work like a servant for his brother Oliver, so he goes to win his fortune in a wrestling contest, where he meets a lady of the court, Rosalind. Rosalind (daughter of the deposed duke) is companion to Celia, niece of the deposed Duke, and when the current duke banishes Rosalind from the kingdom, she, Celia, the court jester (and incidentally Orlando) all end up in the forest or Arden, where the deposed Duke holds court. Romantic mixups, cross-dressing, love poems nailed to trees, and a lion await them all.
