Sisterhood is powerful. Before leaving for a mission in Africa, Runa, a nun, visits her sister three years after entering the convent when her sister stole Runa's boyfriend. Runa comes to forgive and to help her sister make enough money buying and selling some convent property so she can marry. The old boyfriend has new women in his life, but he and the sister tell Runa they're a couple in order to keep the property deal. To make even more money, Runa's sister wheedles large gifts from various men she's stringing along. There are flashbacks to Runa's sexual awakening at the convent. But what are her real reasons to close this deal?
Unfortunately the movie Cloistered Nun: Runa's Confession is not yet available on HBO Max.
