Laura is waiting for her rich and successful husband to come back from work, but she gets a call from him and he tells her that he got extra work and he will be late, so she will stay alone. At some point, she hears a noise in the house and goes to have a look. A POV criminal attacks her and the scene cuts there.

The next scene is camera footage as a message is being recorded for the husband in which she begs him to pay the ransom, or something bad will happen to her. She is tied up, wrists and ankles, on her knees. The recording ends abruptly

Next scene, Laura lies on the floor, still tied up; the creep comes in and informs her that the ransom has not been paid. He starts to grope her feet, takes her bra off and exposes her breasts, then back to worshipping her feet while she squirms and protests. She is soon gagged to make her less loud, and the creep goes on worshipping her feet.

Laura keeps squirming and making noises, so in the end the creep grabs a stocking and strangles her to death. Still tied up, she can't do much but squirm and finally die.
