My Sister in Law
Overview
Intransigent magistrate Viola Orlando is targeted by her rivals who set her twin sister Rosa — a high-class prostitute and pornographic photo-novel star — up to impersonate Viola and demolish her reputation. To complicate things even further, Viola is torn between enforcing the law or giving up her seat on the bench to marry her childhood friend.
