A new leader has risen among the Free Jaffa, K'tano, former First Prime of Imhotep. SG-1, accompanied by Bra'tac, seeks an alliance between the Tau'ri and the large force he has amassed.

El Maestro Bra'tac llega con malas noticias: la esposa de Teal'c está gravemente enferma, y Teal'c se va para estar con ella. Poco después, se abre el portal pero no pasa nada. Entonces Carter descubre una señal de muy baja potencia que está aumentando lentamente hasta alcanzar una sobrecarga lo suficientemente poderosa como para destruir la Tierra.

Mientras exploraba una nave alienígena estrellada llena de pasajeros en criostasis, una fuerza alienígena ha descargado un número de sus conciencias en Daniel.

El general O'Neill todavía está en los primeros días de comandar el SGC y enfrenta un problema importante cuando el recién llegado coronel ruso Alexi Vaselov colapsa en sus aposentos. La creencia de la Dra. Brightman de que Vaselof podría ser contagioso parece ser correcta cuando Daniel, quien estaba con el ruso cuando colapsó, aparentemente enloquece e intenta salir de la base a través de la puerta. O'Neill asegura el SGC pero el problema no es el contagio: la esencia de Anubis está viva y bien, y busca un nuevo huésped.

Un Prior de los Ori ha establecido un campo de fuerza en constante crecimiento en un planeta controlado por los Jaffa llamado Kalana. Un Goa'uld menor llamado Nerus, quien diseñó las múltiples conexiones de la Puerta necesarias para derrotar a los Replicantes, llega al SGC con información sobre el evento y ofrece su ayuda.

Stargate Command gets a video message from Vala's extremely unreliable father, Jacek, on the planet Robak; he claims to know about the late Arkad's plans to attack and blow up Earth, even about the several cloaked, Naquadah-laden cargo ships in orbit, and offers details in exchange for sanctuary. General Landry asks Dr. Lam to help him resume contact with her mother, Kim, his ex-wife. Even after the cargoes are found and blown up, Vala abhors her dad's entry. The general asks her to go easy on him, realizing that he, too, neglected his daughter because of his career, even if Jacek's neglect was just criminal. When Cam and Daniel go tell Jacek he shouldn't scam people, he tricks them into talking to Vala for him. Vala goes over just for catharsis, telling him she's through picking up the pieces of his tricks, and he certainly keeps scamming - as Daniel also finds - even with Terak, a Jaffa from an escaped cargo ship, who hopes to sell the Naquadah. When they are apprehended, Jacek promises to help track it and override the rigging of the cargo ship. The Jaffa wait for Jacek and Vala, intending to eliminate them now that Terak is gone, but SG-1 saves them. Since there never was an override, Jacek cheerfully flies away alone in the cargo ship, ignoring that his treachery was anticipated: it's a decoy.
