Cassie Holland is a tough and feisty former police officer-turned-private detective who takes advantage of her looks to solve cases. Having taken over Lyman 'Shack' Shackelford's agency, she with her loyal ex-con secretary Meryl, and part-time gym instructor Benny, Cassie hits the streets to look for various ex-cons, bail jumpers, petty and major criminals alike to take them down, while she also gets her inside information from Mike Holland, her ex-husband who works in the district attorney's office.
