Detective Goren and Eames are investigating the death of a pretty, petite woman found drowned in her bathtub.
The detectives go to work, turning down a more high-profile case because this one looks interesting. Suddenly, they find themselves awash when a second victim is another petite woman found naked and washed up on shore just days apart. Goren quickly deduces she, too, was drowned in a bathtub. But the case turns out even bigger as a third body is found, with similar body type and strangled but not drowned. Later, a fourth woman is killed.
The investigation leads Goren and Eames to an abusive, cocaine addict lawyer. The connection is that the women were his clients and he also was taking them for a significant amount of money to help feed his gambling addictions. The faithful detectives dig into the case and they know that the shrewd man has one more unknown victim remaining on his list. Since Goren and Eames are unable to get help from his disbelieving wife, they race in a desperate attempt to save the potential victim.
