The Winchester Brothers Go After a Dangerous Creature on 'Supernatural'

Sam (Jared Padalecki) and Dean (Jensen Ackles) look sharp in this still from tonight’s all-new Supernatural.

In “Safe House,” a dangerous creature is accidentally released into an old house, attacking a mother and her child, leaving them both in a coma.

Sam and Dean learn that Bobby (Jim Beaver) and Rufus (Steven Williams) once tracked the same entity so the Winchesters look to the past to come up with a plan to catch the monster before any one dies.

Supernatural airs TONIGHT, March 22 @ 9PM on The CW.
