Q (a.k.a. The Winged Serpent and Q – The Winged Serpent) is a 1982 dark fantasy-horror film written and directed by Larry Cohen and starring Michael Moriarty, Candy Clark, David Carradine, and Richard Roundtree.
The Aztec god Quetzalcoatl, a winged, dragon-like, female lizard, takes up residence in the art-deco spire of the Chrysler Building, with frequent jaunts in the midday sun to devour various hapless New Yorkers. The resulting bloody mess confounds detectives, Dt. Shepard and Sgt. Powell, who are already occupied with a case involving a series of bizarre ritual murders linked to a secret Aztec cult. Meanwhile, Jimmy Quinn, a cheap, paranoid crook who wishes to be a jazz pianist, takes part in a botched diamond heist that leads him to the creature's lair atop the building. This causes Quinn's attempts to settle down and turn over a new leaf from crime to be in vain as he decides to extort from the city an enormous amount of money in exchange for directions to the creature's nest, which houses a colossal egg.
The details of the location fall into Shepard's hands, and he leads a paramilitary assault on the Chrysler Building. First, they shoot the egg, the baby attacks and is killed. Later, the creature comes to the tower. After the showdown, the creature, riddled with bullets, falls onto the streets of Manhattan. Finally, Shepard also apprehends and shoots the Plumed Serpent's crazed priest as he prepares to ritually murder Quinn to resurrect his "god". In the final scene, a large egg hatches.
