When SG-1 travels to Hanka to assist SG-7, they find that a strange disease has killed everyone on the planet except for one little girl. The girl, Cassandra, returns to Earth with Carter and Daniel, but they soon find that the chest pains she is experiencing are caused by a metallic device implanted by the Goa'uld Nirrti as part of a Trojan horse scheme to destroy the Earth stargate. Carter has grown to love the little girl, and as time ticks down, the SGC must find a way to save both the Earth and Cassandra from destruction.

Douglas McLean Memorial Observatory,
- SG-1 was sent to assist SG-7 at the Douglas McLean Memorial Observatory (SGC Project 169) on Hanka to collect data on the accretion disk of a black hole during a local solar eclipse.
- SG-1 had come three months earlier, and the locals had shared their mythology that with the darkness would come the Apocalypse.
- The bacterial infection brought by the Goa'uld contaminated the planet and killed 1432 people including all of SG-7.
- The stargate is made of the element naquadah.
- Cassandra's blood showed traces of naquadah, and a marked potassium deficiency. The object in her chest was made of iron and potassium on one side and naquadah on the other, separated by a layer of fatty tissue decaying at a regular rate.
- The combination of potassium and naquadah causes an intense nuclear reaction with high levels of gamma and particle radiation.
- The Goa'uld Nirrti, an enemy of Apophis, once sent an emissary to negotiate a treaty as a ploy to destroy a stargate taken by Apophis.

Not initially. [O'Neill]
- Well, a black hole is this really big thing, well basically it's a massive... hole, out there. And what happens is everything gets sucked into it, even light. That's why we can't see it, it just gets... sucked in. [O'Neill]
Thank you. [Teal'c]
- It's showtime! [O'Neill]
- Take your time... no hurry... [O'Neill]
