Dance Me to My Song (1998)

A woman trapped in a twisted body from her bouts with the debilitating cerebral palsy communicates with the world via her computer with a voice box. Her caretaker is a short-tempered woman who begrudges the woman the care she needs. Things change when Rose bumps into a young man who starts giving her attention. This leads her to start fantasizing about a real sexual relationship. However, the caretaker takes an interest in the man, as well, which leads to the dramatic conclusion.
