We begin with a priest, who has sent a young lad on a mission to find out information about the Legacy House. The young lad returns with news that a gate way to hell is buried under the Legacy House. The Priest then kills the lad, as he now has what he was after. The priest sets out to be-friend Alex and Rachel (Nick and Derek are not present in this episode). He makes his way into the House where he tells them that the Gateway must be sealed, if it is not, he tells them, Rachels daughter Kat will be killed as she has been struck down with a mysterious virus. As Alex and the Preist make their way underground, the Priest attacks Alex and proceeds to make his way to find the gate and open it. Upstairs, Rachel sees Kristen, who is now an angel, who has been sent to try to stop the opening of the gate. She instructs Rachel to go and stop the priest and to have faith, no matter what. As Rachel finds Alex, they both proceed to the gate, the Priest is about to open it when he notices Rache (thetvdb.com)
