Camp Stillwater is about to reopen after being closed down for years. Deb, the new owner, has thrown her heart, soul and life savings into renovating the camp she loved as a child. She isn’t the only one excited to return as six former campers—Alex, Jessie, Cricket, Joel, Blair and Blotter —join her as counselors hoping to experience the freedom that camp brings now that they are older. Not part of the old crew, Amy is not just new to Camp Stillwater, but to camp in general. While Amy tries her best to fit in with the already tight group, Drew is content to be left alone. As everyone settles in and prepares for the campers’ arrival, Amy is the first to get a feeling that something is not right with this idyllic summer camp.

The campers arrive to Camp Stillwater and quickly Alex and Blotter realize one of their new charges, Anton, is going to be a handful. With the tendency to wander off into the woods talking to himself, Alex and Blotter think the shy kid just has an imaginary friend. But when Anton starts talking about “the Tall Man” and communicating cryptic messages to them, they begin to wonder what lurks in the woods around Stillwater. Meanwhile, flashbacks show how Alex got his “if you want something in life, you have to take it” attitude.

With a string of unfortunate events plaguing the start of the summer at Camp Stillwater, Deb decides to push up the masquerade ball to try and revitalize the morale. But as the campers begin the preparations for the ball, the counselors start to compare notes of the strange occurrences they have encountered. With too many weird things taking place to be a coincidence, Alex, Cricket and Amy are determined to get to the bottom of what is happening. As their investigation turns towards Deb, Joel finds himself in a tricky situation.
