Pay cable channel Showtime premieres the 55th episode of Stargate SG-1. 
A Tok’ra delegation led by Martouf comes through the gate with word that Carter’s father has been capture by Sokar and sent “to hell” – a prison of Sokar’s own design from which only one has escaped: Jolinar, the Tok’ra who briefly inhabited Carter’s body. Martouf places a high priority on recovering Selmak, Jacob’s Tok’ra symbiote, so the Tok’ra can learn about Sokar’s plans to openly attack the other System Lords. But while reaching Sokar’s hellish prison is one thing, getting out of it alive with Jacob in tow is quite another, and Martouf tries to probe Carter for Jolinar’s memories of her escape. Unfortunately, he doesn’t find the information needed to plan an escape until he and SG-1 are already there. Teal’c remains on Martouf’s ship to pick up the team, but Sokar’s ships find and engage him. Trapped on the surface, SG-1, Martouf and Jacob try to take advantage of the chaos caused by an insurrection among the Goa’uld guarding the base. When they wonder why such a bold betrayal is happening before their eyes, everything becomes much clearer when one of the Goa’uld removes his mask, revealing the battle-scarred face of Apophis.
