Output: After the death of his owner Mr. Wing, the mogwai Gizmo becomes the guinea pig of scientists at Clamp Enterprises, a stateoftheart office building in Manhattan, run by eccentric billionaire Daniel Clamp. At the mercy of the chief researcher Dr. Catheter, Gizmo is rescued by his friend Billy Peltzer and his fiancee Kate, both of whom work for the company. Clamp befriends Billy upon being impressed by his skills in concept design, also sparking the interest of Billys superior Marla Bloodstone. Gizmo is left in the office, where water spills on his head and spawns four new mogwai George, Lenny, Mohawk and Daffy who then lock Gizmo in the vents. They eat after midnight, turning into gremlins. After Gizmo finds a way out of the vent, Mohawk tortures him by beating him, shocking him with an electrical wire, putting him in the photocopier, putting Velcro strips on him and ripping them off, and finally ramming him with a toy train while the other gremlins cause the fire sprinklers to go off and spawn a gremlin army that throws the building into chaos. Billy attempts to lure the gremlins into the lobby, where sunlight will kill them; after Billy briefs Clamp on gremlin knowledge, Clamp exits through a secret tunnel to cover the front of the building in a giant sheet to trick the creatures. The gremlins devour serums in the lab; one becomes the intelligent Brain Gremlin, who plans to use a genetic sunblock serum to immunize them to sunlight. One gremlin turns into a female, while a third becomes pure electricity and is trapped in Clamps answering machine by Billy. All the while Grandpa Fred films the chaos on camera with help from a Japanese tourist named Mr. Katsuji. Murray Futterman, Billys neighbor from Kingston Falls who is visiting New York City, encounters a bathybrid gremlin and covers it with cement, effectively turning it into a gargoyle. Murray realizes that he is not crazy and that he has to help; when Clamp escapes the building using his secret route, Murray uses it to sneak inside to aid Billy. Billy and chief of security Forster team up, but Forster is stalked and chased off by the female gremlin. Mohawk finishes torturing Gizmo and devours a spider serum, transforming into a monstrous halfgremlin, halfspider hybrid. He attacks Kate and Marla, but Gizmo confronts Mohawk and kills him with an ignited bottle of whiteout. Outside, a rainstorm frustrates Clamps plan as the gremlins gather in the buildings foyer, singing New York, New York. Billy formulates a plan to kill the Gremlin army: Mr. Futterman sprays the army with water while Billy releases the electric gremlin, electrocuting them. Clamp charges in with the police and press, but sees the battle is over; he is so thrilled by the end result that he gives Billy, Kate, Fred, and Marla promotions and hires Mr. Katsuji as a cameraman. Billy and Kate then return home with Gizmo. Forster notifies Clamp that hes trapped at the highest floor of the building. The female gremlin corners him and entices him to marry her.
