Trying to track down a young woman who stole a winning lottery ticket worth $16 million from them, gangster Jae-cheol and corrupt cop Chung-su follow her to the small island of Mapa. But once they arrive on Mapa island, the two men get far more than they bargained for. The island is so tiny and isolated that no one lives there except five old women - strange crones who have not seen any men in 20 years. Jae-cheol and Chung-su feel like they've been sold at a cattle market, as their hunt for the woman who stole their lottery ticket turns into a nightmare of slave labor and sexual harassment by the grandmothers. But with a full week until the next boat comes to this isolated island, will they be able to recover their money without losing their bodies to these bizarre ladies?
