Blood Lake: Attack of the Killer Lampreys

Ted Jargenson, Shannen Doherty, a city maintenance employee, is checking on a remote roadside pipe when he is attacked and killed by several hungry lampreys.

About a week later, Michael Parker, [Jason Brooks], his wife Cate, [Shannen Doherty], daughter Nicole, [Ciara Hanna], and son Kyle, [Yar Koosha], move to a small lakeside town for the summer. Michael, tasked with controlling the lamprey population in Lake Charlevoix, meets the local fish and wildlife department, consisting of Will, [Zack Ward], Rich, [Fred Stoller], and Marcy, [Rachel True]. They inform him that these lampreys seem to be feeding aggressively on the fish population, effectively destroying it. The mayor, Bruce Akerman, [Christopher Lloyd], demands that Michael fix the problem so that the town can continue to enjoy the tourist revenue.

When Rich sets out on the lake to get a lamprey count, he is killed by the lampreys. His body is found and brought to the morgue. The lampreys burst out from his corpse and kill the coroner, before escaping into the pipes and infiltrating the water system. Despite the deaths, Akerman refuses to shut down the lake. Michael talks to the press in an attempt to warn people. Akerman gets Michael fired in retaliation.

Nicole soon starts a summer fling with local pool boy Alex. Nicholas Adam Clark Alex invites Nicole with him to Ellen’s house, and the two find Ellen’s body in the pool being devoured by lampreys. Hearing their screams, Cate runs next door and calls the police. Ellen, Susie Abromeit, the Parkers’ neighbor, asks Alex to clean her pool as she is out running errands. She intends to seduce Alex by surprising him in the pool.

An officer arrives and he’s promptly eaten by the lampreys, which allows Cate, Nicole, and Alex to escape.

The lampreys attack the town en masse, through pipes and any water sources outside. Cate and Nicole go to find Kyle at the beach while Alex returns to his own family. Akerman is killed by a lamprey that enters his body as he sits on the toilet. Will, [Zack Ward], convinces Michael to help him, and they witness Marcy being attacked and killed by lampreys. They plan to shut down the main water system before the lampreys can escape into Lake Michigan.

They encounter Cate and Nicole, who are busy rescuing Kyle from an attic storage area where he’s barricaded himself. They succeed once Alex shows up with a ladder, and everyone is able to escape. They resolve to use bio salts from the dead lamprey’s livers to lure the live ones to the main water plant where they can electrocute them. They eventually succeed in their plan of electrocuting all the lampreys at the main power plant, but Will is lost to the lampreys. As the town cleans up and Michael and his family leave, having seemingly solved the crisis, a lamprey attacks a member of the cleanup crew.
