Hairstylist Marla Shore joins a fitness club to get in shape, but discovers a dead body instead of an exercise routine. Jolene Myers, a client at Marla's salon, has drowned beneath the frothing waters of the whirlpool.
When Detective Dalton Vail determines Jolene's death was no accident, Marla decides to give her deductive skills a workout and help solve the case. Jolene had few friends at the fancy athletic club.
As Marla gets to know everyone, she wonders who might have targeted Jolene for a lethal soak in the hot tub. When another member turns up dead, she intensifies her efforts to nail the killer and wrap the case. If she fails, the next buff body on its way to the morgue might be hers.
