Allison Kramer suffers recurring nightmares and selective amnesia, returning to camp to discover the truth as the secrets of infamous killer Angela Baker are revealed.

Psychotic Angela is itching to do what she does best: slaughter dozens of teenage campers. As luck would have it, the previous site of her murders has been renamed and converted into an experimental summer camp meant to bring together privileged and lower-class teens. On the day the youths are boarding the buses to camp, Angela runs over a potential camper with a garbage truck and assumes her identity. Once she has infiltrated the camp, the real terror begins.

A young Texas Man who saw his father get killed by a group of bandits, decides years later to go to work for the Pony Express. But he is not just working around the country to deliver mail, he is actually finding the bandits who murdered his father.
