In the wake of a deadly SARS outbreak that’s turned ordinary folks into flesh-eating zombies, Thailand stands alone as the only nation to block the pandemic. That is, until the virus finds its way into a crowded Bangkok apartment complex.
A Thai playboy cons a girl into bed and then leaves her after finding out she is pregnant with his child. She commits suicide alone in her apartment and her ghost haunts those nearby. The apartment block owner calls upon a series of eccentric shamans to exorcise her spirit from the premises.
A young man named Chob, is caught in bed with In-tu-orn, the daughter of a powerful and wealthy landowner who owns almost ever acre in northern Thailand by her father. He asks Chob to prove his love towards his daughter by taking a seven-day trip upcountry, attempting to quarrel with anyone he meets along the way. If Chob can complete this unusual mission he will grant his daughter’s hand in marriage, along with half of his property. One of the first people Chob meets is a northern girl, Nalin, who is unlucky in love and wants to go home to cure her heartbreak but can't afford to travel.
