What is supposed to be the best holiday of their lives turns to horror as a group of teenagers is picked off one by one in a small coastal village.

Based on the biblical story of Abraham and Isaac, from Genesis: “God promised Sarah and Abraham they would have a son, even though she was past childbearing age.” After Isaac is born, to test Abraham’s obedience, God instructs him to sacrifice his only son. As the pious Abraham begins to prepare for the ritual sacrifice, he is stopped by the angel of the Lord and Isaac’s life is spared at the last moment.
