5A TV documentary crew explores murky waters in search of legendary lake monster Cressie, only to dredge up a body instead.

Laura Reagan, host of the cryptozoological documentary series Creature X, and her team are in Newfoundland shooting an episode about Cressie, a legendary giant eel. Things don't start off great: scientific evidence is scarce, stories keep changing, and the locals are throwing a wrench into the production. But what began as a simple TV shoot takes a drastic turn when the crew pulls a body from the depths of Lake Crescent.

For Laura, unravelling the cold case means unearthing long-buried secrets about the most prominent citizens of the remote town of Robert's Arm. With time running out, she and her team must put the pieces together and expose the killer before more blood is spilled.
