Soojin has always known the rules - never bring back anything larger than her palm from the dead, but that was before Mirae died.

The two Han sisters possess a secret unusual gift: the ability to reanimate the dead. Passed down through generations, Soojin and Mirae have brought back countless creatures - though always with the warning never to resurrect anything larger than what they can hold in their palms.

But when eldest daughter Mirae is found mysteriously drowned in the river that cuts through their small coastal town, freshly grieving 17-year-old Soojin can’t resist the impulse to bring her beloved sister back.

At first, the sisters delight in their reunion. But after their sleepy all-American-town is engulfed by a series of harrowing, unusual deaths, Soojin is forced to reckon with the fact that perhaps the sister she brought back isn’t the one she knew.
