When Luce, who lives in a remote part of India, reveals she's soon to die, her identical twin Andromeda agrees to assume her identity to protect their mother from the painful truth. The two sisters will rehearse this transformation over Skype, pushing the limits of the thin line that separates good from evil; love of life from destructiveness; lucidity from madness. But how do you impersonate someone on the inside? Is it possible to love the living with the same love that's reserved for the dead? And is darkness not just frozen light?
