Wet Dreams: Girl From The Dreams (2013)

An intriguing job offer comes to Yong-ho, a fishing boat captain living alone in solitude after divorcing his wife. A female client makes a secret proposal, offering a large sum of money as well as other “things” if he photographs her husband, who is a fishing club member, caught in the act of infidelity. Yong-ho drops the cheating couple off at a secluded rocky island, which is the ultimate “sex spot” on the West Sea, then secretly follows them.
