*With 54 hours before Earth's destruction at the hands of Anubis, Dr. McKay suggests a desperate plan. An electromagnetic pulse sent back through the stargate should destroy the source of the energy buildup that threatens the gate. However, as Carter feared, when the plan is implemented, the energy feedback causes a power surge that destroys the generator and cuts Earth's remaining time in half. Meanwhile, Bra'tac and Teal'c determine the origin of the wormhole connected to Earth, and with Rya'c they arrive by ship at Anubis's planet. There they find technology of alien design sending a beam of energy through the stargate. *Source: Back of card
