In an eerie, deceptively placid near-future, a techno-entrepreneur named Karsh (Vincent Cassel) has developed new software that will allow the bereaved to bear witness to the gradual decay of loved ones dead and buried in the earth. While Karsh is still reeling from the loss of his wife (Diane Kruger) from cancer -- and falling into a peculiar sexual relationship with his wife's sister (also Kruger) -- a spate of vandalized graves utilizing his "shroud" technology begins to put his enterprise at risk, leading him to uncover a potentially vast conspiracy.
