Monica is a successful jewelry designer, married to Alex and Clara's mother. All of a sudden, her daughter enters into a deep and inexplicable coma. Just as the doctors are about to give up on her, a strange woman offers Monica a pact: she will save Clara, but in return she must give her two lives. As she sees no other way out, she performs the ritual the strange woman told her to do, using a peculiar stone. To her surprise, her daughter is saved. From that moment on, Monica must deliver two lives in exchange.
