*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. *Source: Back of card
