HyveFest has everything an elder emo could hope for in a music festival; the best bands in the genre, mosh pits, and an ample supply of nostalgia. For Mallory, it's a refuge. When Jared, a popular influencer and notorious bad boy, goes missing during the festival, her safe haven becomes a source of trauma.

Mallory is consumed with guilt over Jared's disappearance. She was the last person to see him alive, and the events of that night are too horrific for her to admit to anyone-even herself. So on the anniversary of his death, she and her motley crew of online friends meet IRL to figure out what happened to him.

She hopes it will be enough to finally put her demons to rest, but instead, Mallory and her friends become trapped inside the same place Jared disappeared. Someone blames them for his death and won't stop until they're all punished. Forced to participate in a series of increasingly sadistic games, secrets they've tried to keep hidden are brought to light.

Tensions rise and even as their trust in each other dissolves, the group must work together to find out what really happened to Jared... Or be picked off one by one.
