Taking place in the late 1800s, a perverse (though she is trying her best to fit in) woman named Sarah goes to the doctors for her recent aches and pains she is experiencing in her lower back. With the new invention of the vibrator, Nurse Alice is more than happy to oblige and try something new on her patient.
Vibrators were created to help with aches and pains all over the body, not primarily for sexual use at this time in history.
