Murderer Charles Lee uses his dying breath to transfer his soul into a doll named Chucky via black magic. As Chucky, he's given as a gift to a boy named Andy, who realises he's alive after Chucky kills Andy's babysitter. Andy tries to warn people of Chucky's intentions while the doll hunts Andy down to make him his next victim. The voice of Chucky, Brad Dourif, really sells the doll's cheeky attitude. Plus, the film was made in the '80s, so the effects aren't as cutting-edge as they were when the film first premiered (aka you can tell the doll is a puppet).
