The assistant of a creepy power couple inexplicably finds herself pregnant. Immaculata feels like an unexpected offshoot of Rosemary's Baby, between its half-open doors and a phobia of fluids.

Separated by the realities of their day to day lives, the twins Rebecca and Carlo find themselves forced to co-habit and find closure to a chapter in their young lives. A thin line between intimacy and unfamiliarity, they are confronted with a shared past and the fragility of their memories.
