Summit (Part 1)

There is a truce among the Goa'uld and the System Lords meet on a heavily guarded space station. The Tok'ra plan to kill them all, but require a human who can speak fluent Goa'uld and Daniel is the only qualified candidate. The Tok'ra create a version of the Reol chemical ("The Fifth Man") for the undercover mission. Meanwhile, Anubis attacks an outpost of Kali on the planet Cerador, destroying two motherships. Lord Zipacna, under orders from Anubis, attacks Revanna, the site of the main Tok'ra base after Vorash.
