Supernatural

CW | 8:00 pm

The 15th and final season races closer to its (probably) apocalyptic conclusion in the penultimate episode "Inherit the Earth," which finds virtually everything on the line — heaven, hell and the human world in between — as Sam and Dean (Jared Padalecki, Jensen Ackles) continue their high-stakes battle against God (guest star Rob Benedict). Meanwhile, a familiar face returns to join the fight.
