Estranged stepsisters Greta and Moo meet to decide what to do with their dead parents' decrepit house; Greta, who needs the money, wants to sell the house, and Moo wants to use the opportunity to get to know her sibling. The one thing they can agree on is that neither of them want to face what's beyond the basement door. In this twisted, psychological two-women thriller, the sisters not only have to deal with their parents passing and their own feelings towards each other but also confront long buried truths and lies, deeply suppressed emotions and ultimately the realization that they may not make it out of the basement alive.
