Based on the comic book series by Charles Forsman, "The End of the F...ing World" sees two 17-year-old outsiders, James and Alyssa, embark on a road trip to find her estranged father, who left home when she was just a child. James, who is convinced he's a psychopath, has decided it's time to graduate from killing animals to something bigger -- and he already has a target in mind. Alyssa, the embodiment of existential angst, feels like she doesn't fit in at her new school despite being quite popular. Together, they get caught up on a trail of violent events that grow increasingly more ominous as their quest progresses.
