Gremlins (1984) plot summary
An elderly man buys a strange and unusual furry creature for his son. All the boy has to do is follow three simple rules: keep it away from bright light, don't get it wet, and, most important, no matter how much it begs, don't feed it after midnight. When the boy makes a few errors the creature accidently spawns a horde of nasty and unfriendly offspring who wreak havoc and enjoy doing it.
