Movie where no adults exist & the teens begin to devolve

The film follows a young man that's trapped inside of a post apocolyptic high school, as he attempts to escape in order to live a normal life.

Teenagers with neglectful parents run amok; some get killed, some get arrested, some get rehabilitated.

A group of teenagers wake up to a world where the adults have mysteriously disappeared and all technology has ceased to function.

Set in a near-future where earth has punished all adults for not taking properly care of our planet. We follow a group of kids, left all by themselves in a trashed world, living day by day and trying to avoid the unknown future. The kids put all their fear into hating the adults, but what will happen when one of the kids starts to become one?

Teen-Age is another "exposé" film of the 1940s, cheaply made but widely distributed. In the guise of a warning against wartime juvenile delinquency, the film offers the exploitational tale of a bunch of wild, unsupervised kids at large in a small community. With nothing but time on their hands, the young protagonists become involved with petty theft, inevitably leading to some pretty serious consequences.

Some time not far from now, it was decided that adolescents were detrimental to a well-functioning society. Upon turning thirteen, teenagers were quarantined onto an island within the city, colloquially known as Teenland. At the age of 18, the inhabitants of Teen-land are forced to join adulthood. The memories of their childhood are erased and they start a new life In this slightly dystopian scape, lives a band, The Nuclear Toads. After being rounded up to be processed for adulthood, they manage to escape and buy themselves one last night of adolescence in which they will perform their final show. This film is the story of that night.

A group of teenagers find themselves shipwrecked on an uncharted island off the Mexican coast. Faced with the prospect of a long-term stay, the island soon degenerates into a struggle between two groups; teens who want high school to end as fast as possible, and teens who never want high school to end.

A doomsday virus of madness and death has destoyed the world's adult population. Only the young survive. They watch in horror as their parents go mad and die. Haunted by terrifying memories, they fight for life in a bleak wasteland. Gangs of teens and outlaw children roam the scarred landscape. Sisters Evie and Fran keep to themselves, two outsiders gathering food and moving from town to town.

It's the 1980's and a group of typical horror movie high school kids are getting together to hold a séance in a haunted house. Naturally, people start dying preposterously bloody deaths, girls are getting naked for no apparent reason and people walk into pitch black rooms and say things like "Is someone in here?" Will any of these poor, hapless kids survive? Or will their bodies fill the house with blood and...well, you know!

A masked killer, a cabin in the woods, a group of teens: the basic ingredients of a very old story - but when the killer accidentally dies, the kids discover they cannot leave.
