They Wait on AllMovie

When a family of three returns to America for a family funeral after living in Shanghai for the past three years, a desperate mother races to save the life of her suffering child upon discovering that he has fallen victim to the wrath of a living corpse. Sarah, Jason, and their young son Sammy were living halfway across the world when they were summoned back home to pay their final respects to a beloved family member. Shortly after the funeral, however, an already grim situation takes a heart-wrenchingly bleak turn when Sammy falls mysteriously ill and appears to be on the brink of death. Failed by western medicine and desperate to save her ailing child, Sarah seeks out the assistance of a mysterious pharmacist who informs her that young Sammy is now in the grip of a living corpse. With precious little time left to appease the spirits before Ghost Month ends and their child is lost forever, the parents must now accept that fact that forces beyond their comprehension are at work and respond quickly to the demands of the dead before it's too late.
