Steel and Lace (1991)
Gaily Morton (Clare Wren), a classical concert pianist, is raped by businessman Daniel Emerson (Michael Cerveris). Her brother Albert (Bruce Davison) takes time off from his career as a robot scientist to represent his sister at the criminal trial.
However Daniel has gotten several of his friends to provide an alibi for the night of the rape, and he is found not-guilty. Gaily is horrified by the verdict and leaps from a tall building, despite her brothers pleas.
Albert uses his knowledge of robotics to resurrect his sister as a cyborg, which he then sends after Daniel and his business partners; the five men who provided false witness in court.
