****SPOILERS**** Driven almost beyond endurance by her mom former Olympic bronze medal winner Gina Morgan, Keesha Sharp, high school swimming star Samantha,Javicia Leslie,gets help for her new assistance coach the likable lad Bryce Hinge, Tom Maden. It's Bryce who soon turns out to be a bit unhinged himself in his obsession with Samantha's looks swimming ability but most of all her massive mop of hair, that must weigh at least 10 pounds,that if she trimmed it down would add or cut down at least five seconds to her final swimming score. At first trying to be professional with his giving Samantha hints to improve her swimming by using shorter strokes Bryce soon tries to get her to put out for him, in the swimming pool, after classes that soon turns disastrous for both of them.

Not only concentrating on Samantha Bryce starts to drop hints to her that her mom's bronze medal was tainted by her winning it while being high on steroids. Bryce also goes after Samantha's boyfriend Lucas,Cameron Jebo, who was on to him and tried to warn her away from Bryce. That leads Lucas getting almost beaten to death by a hooded Bryce with an aluminum baseball bat in the school parking lot. It soon becomes apparent that the All-American looking Bryce in a psycho in disguise! That's confirmed by his estranged dad Mr. Thomas Hinge, Ivar Brogger, who told a shocked Samantha that his son is a accident just waiting to happen.

***SPOILERS*** It's when Bryce at first fails to satisfy-sexually-Samantha's classmate Emily,Madison Iseman, who was more then willing, unlike Samantha, to put out for him he takes his frustrations, in not being the great lover that he thought he was, out on Samantha's mom Gina whom he ties up in her living-room and holds hostage. It's in fact Emily who finds and rescues Gina before Bryce can do any harm to her. Back at the swimming pool Bryce forces at gunpoint Samantha to undress and take a dip with him only to have her grab his gun, not his you know what, and try to keep the love crazy guy at bay until the police-Whom her mom called- arrive. It just happened that Samantha was a bit too quick on the trigger when Bryce stripped down to his boxer shorts attempted to make a move on her that ended up her deep sixing him.

At first glance, "Killer Coach" is about a champion swimmer on the receiving end of harassment by a deranged male coach. But, as is the case with many Lifetime films, the real story is about the bonding of a mother and a daughter.

Samantha Morgan is a superb swimmer, and her principal coach is her mother Gina, a former bronze medalist swimmer herself. But Coach Morgan passes the duties on to an assistant named Bryce Hinge, whom she has hired primarily as a more impartial mentor to her daughter with upcoming trials. Samantha's mother believes that her daughter has the potential to take home the gold.

It turns out that Bryce Hinge is an predator, and he is instantly besotted with Samantha. But after Bryce is rebuffed, he truly becomes unhinged and threatens to expose Samantha's mother, who allegedly used HGH to win her bronze medal. Samantha is then in the direst of circumstances as she tries to simultaneously fend off Bryce and to protect her mother.

One of the most interesting scenes in the film is when Samantha travels outside of L.A. to meet with Bryce's father, who was a former swimming commissioner. The father knows of Bryce's mental condition that may have stemmed from his mother's suicide when he was age ten. The father clearly senses that Samantha is another victim of his predator son, yet fails to take any action to prevent the abuse.

Other interesting characters are Lucas, the boyfriend of Samantha, who valiantly tries to assist her in getting out of a bind. There is also Emily, a fellow swimmer, who is both a friend and a rival to Samantha. Then, there is the fatally flawed Bryce, who is constantly grinning with the phony smile that is his trademark device as a predator.

But the heart of the film is the touching mother-daughter relationship. While Gina and Samantha have grown apart and there is tension during the period in which the smooth-talking Bryce is harassing the daughter, the mother's love comes shining through at the time it is needed the most.
