->''There's no place to hide on... the Day of the Animals.''

A 1977 nature horror film directed by William Girdler (''Film/{{Grizzly}}'', ''Literature/TheManitou'').

A group of people take a backpacking trip through some mountainous terrain. Their timing is rather unfortunate, since the [[GlobalWarming ongoing depletion of ozone layer]] has exposed the animals to higher dozes of UV-radiation, which has driven them mad. "Mad" as in "they all target humans specifically".

!!This film has examples of:

* ArtisticLicenseBiology: In what is almost the last line of dialogue in the entire movie, it's stated that a 'virus' caused all the homicidal behavior by the animals. Not many viruses affect raptors, bears, cougars, dogs, rats, wolves, tarantulas, rattlesnakes, and New York Ad Executives in the exact same way.
* AttackOfTheKillerWhatever: ''All of nature''. Or at least the one residing in elevated terrain.
* AttemptedRape: Jenson, in his newfound alpha male fervor, decides to rape Beth since he "killed a man for her" and thus thinks he now owns her.
* BearsAreBadNews: A bear makes a well timed appearance to stop Jenson raping Beth. He then tries to wrestle the bear, dying in the process.
* TheEndOrIsIt: The film ends with the eagle, that has seemingly been leading the animals, flying at the screen, suggesting that danger is not over yet.
* FailedASpotCheck: During the first leg of the cast's journey, they consistently fail to notice the various dangerous animals that are watching them at close proximity.
* GhostTown: After an arduous journey out of the woods, Frank and the little girl who joined him on the way find the nearby town evacuated, with only animals and a couple of corpses in sight.
** Also happens earlier when the campers find an abandoned and torn-apart camp with no sign whatever of the campers. This ''after'' encountering some oddly violent animals. [[TooDumbToLive They decide to stay there anyway]].
* [[GreenAesop Green]] SpaceWhaleAesop: Don't deplete the ozone layer or the extra solar radiation will mutate a virus and turn animals (and Leslie Nielsen) into homicidal maniacs.
* ImpaledWithExtremePrejudice: Jenson kills Beth's boyfriend by impaling him with his walking stick.
* {{Jerkass}}: Even before driven over the edge by the hotter-than-usual sunlight, Jenson acts like a total dick to everyone.
** JerkassHasAPoint: Painful though it is to admit it, if the group had backtracked when Jenson first suggested it, they might have all made it back to civilization safely without anyone becoming animal chow or turning on and raping/murdering someone else.
* LeftForDead: Due to the relentless onslaught by a pack of dogs, two cast members are left for dead as the remaining ones flee for their lives.
* TheNicknamer: Jenson refers to everyone by the nicknames he has given to them, "Hot Shot" for Buckner, "[[Franchise/TheLoneRanger Kemosabe]]" for Santee, and so on.
* NoEnding: The remaining survivors all hide out in a grounded helicopter, raft downriver to escape some killer dogs, or hide in a pickup at the end -- and the animals all conveniently drop dead from the "virus". Save for the evil eagle, that is.
* {{Novelization}}: By Donald Porter.
* OpeningScroll: The film opens with text that tells about the depletion of ozone layer, and how the events in the film are something "that might happen".
* ReptilesAreAbhorrent: When Frank finally makes it into civilization, he runs into two cars filled with snakes, [[spoiler: the second one leading to his death]].
* SavageWolves: As the cast sleeps, a lone wolf suddenly attacks Mandy and scars her face badly. This forces her and her husband Frank to split up from the others to get to the local forest ranger station.
** A much bigger pack chases three of the survivors into a grounded copter before they (the wolves, that is) just up and die.
* SpiritualSuccessor: To William Girdler's previous film ''Film/{{Grizzly}}'', for sharing the similar location, plot, and some of the cast.
* TheCobblersChildrenHaveNoShoes: Buckner, in spades. Every death from those in the group are, even if indirectly, his fault:
** He fails to notice the danger they're in despite the strange behavior of the animals, including the continuous attacks, until it's too late.
** He is not suspicious at all that they find a deserted campsite with the belongings of the campers all in there, and even during the nighttime and the following day, after wolves attacked his group and injured one of them, he chooses to ignore the fact that these missing people haven't returned.
** He continues to press on his original planned path rather than turn back and go to where he first sent Frank and Mandy, where there is a radio, buildings to hide out in, and is a shorter trek than the path he has the group take to reach civilization. This after the group discovers that the stash of food he had been leading them to has been ransacked by the animals.
** He brings along absolutely no weapons or form of communication in case of an emergency.
** And possibly the worst of all is, after Mandy has been attacked by wolves, he sends Frank and the injured Mandy on a different route all by themselves to find help for Mandy, despite the fact that they are his responsibility and they have absolutely zero survival skills or know-how of how to survive in the forest, which is, ironically, the very thing Buckner is paid to do and is supposed to be teaching them.
* WalkingShirtlessScene: Jenson stops wearing a shirt when he and couple others split from the main group.
