In a seedy hotel room, two twins take shelter. One is tormented by the guilt of a crime she committed. Meanwhile, the sister sleeps by his side, immutable, without compunction for his actions. Consciousness takes the one who is awake, surrounds her and shakes her in a tortuous whirlpool of emotions that play with her mind, twist her, manipulate her and absorb her, threatening to cross the fine line that separates her sanity from the most absolute despair.
