In April 2020 during the COVID-19 pandemic, college student Parker Mason takes her best friend, Miri Woodlow, to her family's lake house to quarantine her. They arrive at the luxurious and secluded lake house when Parker receives a cryptic text message. The girls head to a small dock to get a tan and Parker receives another message that unnerves them both. From that moment on, all the tranquility they were looking for turns into a fight for their survival.—Mahou 5 star
