Skirt-chasing, wise-cracking, dysfunctional Private Investigator Dev Haskell leaves his usual stool at the Spot Bar to take on what looks like a cakewalk job: keep ice cream mogul Mr. Swirlee alive. Turns out Mr. Swirlee is anything but a cakewalk... He's a ruthless "entrepreneur" with a flash temper, a mean streak a mile wide, and a laundry list of people who want to do him in-including his sex-crazed girlfriend, Lola. Things go from bad to worse when Dev discovers his client is running a gambling ring in his ice cream trucks. When Dev's revelation is detected, a dead body ends up in the trunk of his car. Once again, our hero is in over his head. Thank God for Dev's sometime friend, felon Tony "Dog" Colli, who agrees to help out.
