Description
Eighteen-year-old Liz Taggart has gone to a lovers' lane with her boyfriend, Owen Clark, who has not yet been introduced to her parents. Unbeknownst to them, a childlike peeping Tom named Harold Loftus has been watching them. Loftus knocks Owen unconscious and overpowers Liz, taking her to a shack.
A couple on a motorcycle try to revive Owen with liquor, but they leave when he doesn't wake up. Police arrive and mistakenly conclude that Owen is drunk. At the station, night-shift captain Ed Bates hears the story and realizes that Liz is the daughter of the day-shift captain, Dan Taggart.
While holding Liz prisoner, Loftus kisses her against her will. Loftus' mother, Mabel, phones police when her son does not return home. Liz manages to get hold of Loftus' gun, but she finds it's not loaded.
Taggart is furious with Owen, blaming him for what has happened; but his wife scolds Taggart for intimidating their daughter to the point that she kept her relationship secret. When the police officers find the shack, Owen saves Taggart's life by leaping on Loftus at the last second. Taggart begins beating Loftus, who cries out for his mother.
After Loftus is taken into custody, Taggart invites Owen to accompany Liz back home.
