University lecturer Han Yu came to Thailand because of a letter, only to be attacked late one night. When he woke up, he found that everything from his clothes to his hairstyle had changed, and, for some inexplicable reason, he had ended up in a Thai black prison, caught in a prison power struggle...
Meanwhile, at Han Yu's university, Ba Yu, once a member of a Thai gang, took his place as a lecturer. He taught in his own way and uncovered the dark secrets behind the Eden Garden Genetic Project.
Are they twin brothers, or another version of each other in this world?
