1934: Something is deadly wrong with the lake...

When Chief Petty Officer Charles Emery receives a cryptic, urgent message from his old mentor, Captain Donovan, he immediately responds - and finds himself in a lake-side resort town in the grip of an unknown terror. Someone - or something - has been attacking swimmers and fishermen. And Captain Donovan is convinced he knows why.

Donovan believes there is a monster in Deep Water Lake and he has the scars to prove it. But everyone knows that monsters don't exist, so the locals want to lock Donovan away in an asylum. Donovan's daughter, Norah, is determined to save him at all cost. Caught in the middle, Emery has to either prove the unprovable... or condemn his one-time hero into a mental institution.

As the mystery deepens and Donovan slips further into his dark fantasies, can Emery discover the truth behind the Monster of Deep Water Lake? Or is he already too late?
