Eighteen-year-old Jenna is sharing a flat in Brohl, Germany, with her friends Caro and Merle when a girl is killed nearby. The murder seems to have parallels with two other frightening crimes. Then one day, Caro is found murdered - stabbed seven times and with her necklace missing, just like the other girls. At the funeral, Jenna swears revenge in front of everybody, and in turn attracts the attention of Nat, a handsome and mysterious strawberry picker. With Jenna sidetracked by love, Merle sets about solving Caro's murder herself. But as the answer dawns on her, another horrifying reality emerges.
