Harpies plot
Jason Avery is an ex-cop and now works as a guard at a museum. But then armed thieves break in, after a valuable statue that looks like some kind of crystal dinosaur egg and is said to have special powers. The thieves manage to steal the statue and a scientist gains control over Harpies (winged female demons) through the statue's powers. Through supernatural events, the statue teleports Jason back in time a thousand years and ends up in a land threatened by Harpies. Jason wants to return to the present and is very worried, but the villagers see him as a great hero who can defeat the Harpies.
