Which people want to kill Ned for money?
Ned Ravine, who is both a police officer and lawyer (who often defends the people he arrests), believes that he knows everything about women, and says that he will throw away his badge if anyone ever proves him wrong. While on a stakeout, he encounters a seductive woman named Lola Cain; the next day, Lola shows up at his law office, saying that she needs him to look over some papers she has come across. Meanwhile, Max Shady, who was just released from prison after seven years, starts stalking Ned, planning to kill him for failing to successfully defend Max in court.
Ned's wife Lana and her car mechanic Frank, with whom she is having an affair, start plotting to kill Ned in order to collect on his accident insurance, which has a triple indemnity rider; if Ned is shot, falls from a northbound train, and drowns in a freshwater stream, Lana will collect nine million dollars.
Lola gets Ned to come to her house to examine the "papers", which are actually a laundry receipt and an expired lottery ticket, and the two of them end up having sex in various wild ways. The next morning, Ned says that they can never do that again because he loves his wife; this drives Lola to start stalking Ned.
A few days later, Ned takes the train to go to a legal symposium; Lana and Frank are also on the train, and so is Max. When the train passes over a lake, Lana shoots Max 36 times with a revolver, mistaking him for Ned, and he backflips through the door to his death; Ned thinks that Lana had acted to save his life. He arrests Lana, and then defends her in court, getting her cleared of all charges. Lana later kills Frank, believing that he was going to abandon her, by pinning him against a wall with his power drill; Lola witnesses this, and starts blackmailing Lana.
