Scar (2007) on Netflix

Plot summary

Joan Burrows comes back to Ovid, Colorado, for her niece Olympia's high school graduation. Years before, when Joan was seventeen, she and her friend Susie were kidnapped by an undertaker and serial killer named Bishop, who bound them to autopsy tables, torturing one girl while the other could end it by asking for her death. Joan escaped, believed she had killed him, and carries a scar on her cheek. Before the graduation, a young couple goes missing, and a mutilated body is later found in the water at a town festival. As the deaths mount, the question becomes whether Bishop is still alive or a copycat has taken up his work.
