As the story begins, private investigator Melody Marks receives a cryptic video: her friend Bunny Colby is tied hand and foot, and she makes a desperate plea. She tells her that they have her aunt Cathy, and that Agent Darla is involved, although she doesn't know what that means. Melody uses her inside sources to locate the rogue agent Darla Crane. To infiltrate her hideout, Melody dresses up as a Camp Scout, and knocks on Darla's door using the ruse of selling cookies. The stunning redhead invites her in, but Darla isn't fooled by her deception and immediately takes Melody captive. Agent Crane binds the detective's hands and feet, cleavegags her (all tying and gagging is shown on-screen) then strip-searches the gorgeous gumshoe. Ultimately Darla finds a tiny surveillance device that Melody was planning to install, then she hogties her snoopy guest. The busty agent then leaves Melody alone to make inquiries about the detective, and Melody squirms and struggles in vain against the ropes.
