"Just call it 'Q'. That's all you'll have time to say before it tears you apart."
Q (a.k.a. The Winged Serpent and Q – The Winged Serpent) is a 1982 monster film written, produced and directed by Larry Cohen and starring Michael Moriarty, Candy Clark, David Carradine, and Richard Roundtree.
Plot
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 helpless New Yorkers on the rooftops. The resulting bloody mess confounds detectives, Shepard and Powell, who are already occupied with a case involving a series of bizarre ritual murders linked to a secret neo-Aztec cult.
Meanwhile, Jimmy Quinn, a cheap, paranoid crook who wishes to be a jazz pianist, takes part in a botched diamond heist. Attempting to hide from police after the heist, he stumbles upon the creature's lair atop the building. Quinn abandons his attempts to settle down and leave his life of crime, deciding to extort from the city an enormous amount of money in exchange for directions to the creature's nest, which houses a colossal egg.
Quinn makes a deal with the city–$1 million for the location of the nest. He leads Shepard and a paramilitary assault team to the top of the Chrysler Building. First, they shoot the egg, killing the baby inside. Later, the creature comes to the tower. After the showdown, the creature, riddled with bullets, falls onto the streets of Manhattan. Finally, Shepard shoots the Plumed Serpent's crazed priest (who had been committing the ritual murders) as he tries to kill Quinn to resurrect his "god".
Ultimately, a second large egg hatches in a different location in the city.
