Girls in her position give up their names and their lives; they're sold as lots. This story is about Melinda, Lot 21. Following the death of her owner, Lot 21 is brought to the State Detention Center where it becomes her counselor Sydney's job to determine if she is to be reassigned or set free of the 'service contract' she agreed to - a modern day attempt to alleviate prison overcrowding, which has become little more than institutionalized prostitution. Sydney despises this devious twist in the legal system, but as she interviews Lot 21, she's intrigued, even aroused, by the sordid tale this curious naked girl has to tell about the slave life she deliberately sought out. A shocking journey into the eroticism of S&M.
