After her sister Valerie quits the family detective agency - she tired of being stripped, bound, gagged and having a dildo inserted in her private area by crooks she was investigating - Melanie Rios must find a replacement quickly. She selects the beautiful, if inexperienced blonde Carly Banks, who promptly makes a rookie mistake, causing both operatives to be tied and muzzled by crooks. When the plucky investigators ignore the criminals’ warning and continue to work on the case, thugs grab them, strip them naked and force them into the trunk of a car that’s abandoned in the desert.
