A man, Ryan (Charles Dera), has an erotic obsession with twins and engineers a situation where he marries and divorces one woman to have a stepdaughter, Alisha (Kimmy Kimm), then marries another woman so that he can have another stepdaughter, Madison (Lulu Chu), who looks just like Alisha.
Ryan seemingly wants them to all be one big, happy family but the stepdaughters start to get suspicious and weirded out when Ryan's behavior changes. Especially one day when he gifts them matching dresses to make them look even more alike than ever before...
The stepdaughters then get a shock to the system when Ryan announces that he's divorcing Madison's parent and that he wants Madison to stay with him and Alisha so that they can continue being a family. But Madison carefully says that she's going to stay with her parent instead. Ryan seems to understand... but when Madison's parent later pass away under mysterious circumstances, both stepdaughters realize that something's horribly wrong.
