The End of the F***ing World (2017)

Teen outsiders James, a self-diagnosed psychopath looking for a human victim, and Alyssa, the personification of existential angst, decide to escape from their families and embark on a road trip to find Alyssa’s estranged father. As the pair get caught up in a series of violent events, they find themselves on a journey of discovery that becomes progressively ominous, trailed by two similarly mismatched police detectives.
