It is later revealed that she actually castrated him. The film ends with Miranda visiting her father, stating that William will not be coming around any more.

“Return to Sender” is dreck of the lowest kind—a sleazy exploitation film that is all the worse because it has somehow convinced itself that it is thoughtful and profound. For anyone interested in a well-told story, its failings at the most basic narrative levels will seem appalling.

This is the story of a woman (Rosamund Pike's Melinda) who is raped, who then emotionally connects with her rapist (Shiloh Fernandez's William) while he's in prison, has him think that she might want him sexually, and then when he gets out, she traps him, performs some type of surgery on him, and then murders him.

Rotten score. Rotten audience score. A traumatized nurse (Rosamund Pike) hatches an elaborate revenge scheme against the man (Shiloh Fernandez) who raped her on a blind date.
