The Parker's are a reclusive family hiding a dark secret. When their matriarch dies, the two oldest children grapple with the truth about their familial past and whether or not their secret family traditions need to be continued. But they might not have a choice in the matter either way, as a torrential rain is threatening to reveal over a century's worth of their family's dark deeds to a town that's already close to the brink.

A disease that only targets children, and causes them to become increasingly and murderously violent, is allowed to run amok in one particular household thanks to an extreme case of denial and their parents inability to exhibit any kind of common sense or basic observational skills.

Some snowmobile riders get stuck and stranded during a blizzard and take place shelter in an abandoned religious summer camp lodge. As they investigate their surroundings further, they discover that the supposed Christian lodge may not have been on the up-and-up, and was actually the site of some mysterious incidents. Naturally, they ignore all this, and decided to play with the creepy Ouija board they find in a closet. It doesn't take too long after that to realize that their little game may have inadvertently released something supernatural...and malicious.

The crazed doctor breaks out of the loony-bin and tries to set up a new life by hiding out in a small town. But just when he starts to think he finally has control of his violent impulses, one simple misunderstanding again SNAPS his grip on sanity, and he falls once more into a spiral of depravity and murderous intent. Oh, and dental torture...Lots of uncomfortable dental torture.

The killer turkey returns to try to get his wings on the last remaining copy of Thankskilling 2 (which doesn't exist), all so he can take it to Turkey Hell and use it as an ingredient in a machine to try to destroy humanity....somehow. Not that any of that matters, because you spend most of the movie following Yomi, a hapless, unrelated hand-puppet who has literally lost her mind, and her quest to stop the evil, fowl beast.

After one too many stressors, a popular dentist just SNAPS, and goes on a torture and killing spree involving some of his patients.

Basically the same plot as the first film, except this time it's a newspaper reporter being sent into the swamp to investigate some stories about illegal dumping. The giant Croc returns. More people die. Characters from the last film return. And individuals keep inexplicably jumping out of their boats, right into the crocodiles reach. It's the darnedest thing.

In this blatant Jaws rip-off, a group of young environmentalists inspecting a rumored radioactive dumping sight in the swamp, get more then they bargained for when they encounter an abnormally large crocodile that seems to have developed a taste for human flesh.
