below is a synopsis for hammer of the gods (5x19) =)

Sam and dean are kidnapped by a group of gods (Kali; Ganesh; mercury; Zao Shen & Baldur) & held hostage in a small hotel. The gods want to use Sam and dean as bargaining chips to stop the apocolypse, but Gabriel shows up and warns them that if lucifer finds them he will kill them all, unfortunatly one of the gods turns on the rest & lucifer appears.

I'll post a new synopsis for the next episode in a few days =)
