La trama de Air nos sitúa en unas instalaciones de conservación criogénica donde dos guardias de seguridad patrullan constantemente sin poder salir del lugar, ya que una guerra nuclear ha convertido el aire exterior en irrespirable. Ambos custodian a los científicos durmientes que, llegado el día, saldrán a la luz para reconstruir el planeta, pero poco a poco el claustrofóbico entorno comienza a hacer mella en su cordura.
The year is 1910. The West is dying. The American frontier is undergoing a violent transition from the ways of old to modern times, and Mexico has entered a prolonged period of bloody civil war. Reformed outlaw John Marston is on his way to capture former running buddy Bill Williamson when he comes upon a half dead snake oil merchant named West Dickens. Marston travels under a bleak and unforgiving sun, teaming up with a violent sheriff and a colorful mentally deranged grave robber and together they discover a bloody massacre of homesteaders left in the wake of Williamson. They hatch a plan to break into an abandoned fort where the Williamson Gang is holed up - and a dark, surprising twist ensues.
