Friday the 13th Part 4: The Final Chapter (1984)
Picking up directly after the events of part 3, all the bodies are collected up and taken to the local morgue. However, Jason isn't really dead and at the apropriate moment, arms himself with a surgical hacksaw and a scalpel and promptly does away with the 2 mortuary staff. He then heads back over to Crystal Lake to carry on where he left off and comes accross a couple of holiday homes which are located a bit further round the Lake. Staying there are the Jarvis Family in particular, 12 year old Tommy. Accross from them are another group of imbecilic drunken teens, staying at the house opposite. But when he turns his attentions to the Jarvis household, 12 year old Tommy, being a horror enthuiast, manages to play him at his own game and with some help from his sister, finally brings Jason's reighn of terror to a grisly halt.
