Thirst

Sang-hyun (played by top Korean star Song Kang-ho, of The Host) is a priest who cherishes life; so much so, that he selflessly volunteers for a secret vaccine development project meant to eradicate a deadly virus. But the virus takes the priest, and a blood transfusion is urgently ordered up for him. The blood he receives is infected, so Sang-hyun lives - but now exists as a vampire. Struggling with his newfound carnal desire for blood, Sang-hyn's faith is further strained when a childhood friend's wife, Tae-ju (Kim Ok-vin), comes to him asking for his help in escaping her life. Sang-hyun soon plunges into a world of sensual pleasures, finding himself on intimate terms with the Seven Deadly Sins.
