Sabrina is an Olympic hopeful who falls short for the summer games and is rejected by her married coach. When he tries to stop coaching Sabrina, she first attempts to seduce him in public and then tries to kill him in the pool by holding him underwater in a bear hug. After some time in depression, Sabrina rebounds, much to her mother's delight. Sabrina takes a job as a swim instructor and fixates on the child's father, Parker. His wife, Ellen, is in rehab for neglecting her daughter by the pool while on a bender. Sabrina wins over the child and hopes to win over Parker next. Sabrina's mother notices her daughter obsessing over Parker and tries to send her daughter back to therapy. Sabrina has been fixating on older men ever since her father left. She blames her mother. When Vickie tries to call Parker to warn him, Sabrina smashes her mother in the face with a cast-iron skillet, killing her. Sabrina puts her mother's body in the bathtub and pours sulfuric acid on the body to break it down. [ The swim lessons continue, and Parker invites Sabrina to stay over for dinner. They enjoy some wine while Parker shares about Ashley almost drowning while Ellen wasn't watching. Sabrina kisses Parker, and he tells her that even though he is attracted to Sabrina, he is a married man who is committed to his wife. Speaking on his wife, Ellen is let out of rehab and returns to the home unexpectedly. When Ellen meets Sabrina, she is threatened and clearly not a fan. Ellen ends the swim lessons promptly and accuses her husband of flirting with Sabrina. Sabrina comes up with a plan to get Ellen back to rehab. (which is hiding a liquor bottle under the sofa.) Ellen almost relapses but dumps a tiny bottle of gin down the drain when she sees a photo of her daughter; she also notices a family photo has been stolen from the mantel. Ellen hires a new swim instructor named Donna, who knows about Sabrina's past with her coach and is an Olympic bronze medalist. Sabrina makes roofie cookies and brings them over to Ellen and Parker's home. Ellen eats one and starts to feel drowsy instantly. With Ellen passed out, Sabrina gets Ashley in the pool and then lets her swim in the pool by herself since she has gotten so good. Parker comes home and finds his wife passed out and Ashley in the pool alone swimming. He accuses his wife of falling off the wagon. Ellen maintains her innocence, but Parker insists on sending his wife back to rehab while Ashley cries outside. Donna and Sabrina have a very random swim-off. Sabrina wins, but Donna lays into her for lying. Donna realizes that Sabrina is a murderer and tries to call for help, but she is drowned just like the coach. With Ellen AND Donna out of the way, Sabrina is back teaching lessons with Ashley while Parker watches. She also enjoys dinner with them and tucks Ashley into bed. Then the grown-ups go for a sexy night swim and later make love on bed. Parker will be out of town for a few weeks and invites Sabrina to take care of Ashley while he is away. They have some more sex before he leaves. Ellen is working the steps in AA, but she is itching to get out of there and tracks down Coach Sharky. Ellen steals a nurse's keys while they aren't looking and meets with the coach. He warns Ellen that Sabrina is deranged because she tried to kill him. He didn't tell anyone because he didn't want to ruin her life. Ellen realizes that her family is in serious danger. While driving to her house, Ellen phones Parker and warns him about Sabrina. Parker has already put things together and confronts Sabrina with the truth he has learned. He realizes that Sabrina is obsessed with him when she presents him with a photo-shopped picture of three of them as a family. Parker tries to call the police, but Sabrina tries to drown him awkwardly. Ellen arrives on the scene and takes Sabrina out with a tire iron. She rescues her husband and performs CPR to resuscitate Sabrina so the police can arrest her. With Sabrina gone, the family is free to splash around the pool. (thanks to lifetimeuncorked)
