Max Cartwright (Taissa Farmiga), a high school senior, is mysteriously transported with her friends into a 1980s horror film that starred Max’s mother, Amanda (Malin Åkerman), a celebrated scream queen. Trapped inside the movie, Max finds herself reunited with her mom, who she lost in real life. Together with Max’s friends, they must fend off the camp counselors’ raging hormones, battle a deranged machete-wielding killer, and find a way to escape the movie and make it back home.
The film also stars Alexander Ludwig, Nina Dobrev, Alia Shawkat, Thomas Middleditch, Adam DeVine, Angela Trimbur, Chloe Bridges and Tory N. Thompson and is directed by Todd Strauss-Schulson from a script by Joshua John Miller and M.A. Fortin.
