Black and White are twins with a powerful connection. After their parents' separation, White's father took him out of the country, their family effectively severed in two. It isn't until more than years have passed that White--now grown--returns to Thailand. One day, seemingly from nowhere, White feels an agony like death. He recovers in the hospital, but they're unable to determine the cause. Then, he picks up a call from a childhood friend, Tod. Tod tells him that Black is in a coma following a vicious attack and he learns that Black is in a motorcycle gang. Unable to endure the harm done to his brother in silence, and suspecting it was one of Black's close friends--Sean, Gram, or Yok--who betrayed him, White disguises himself as Black to root out the traitor. But White doesn't know his brother as well as he thought; he's not behaving like the Black Sean knows, distrustful and uncaring about the feelings of others. Sean's suspicious. The difference gets under Sean's skin and makes him feel things he shouldn't.
