When cryopods containing dead planterary explorers are brought to the Nelson Mandela Medical Space Station to be examined, they are delivered to the Quarantine level, as per protocol. It falls to Dr. Al-Fadi and Dr. Grace Lord to examine the first explorer and they unwittingly release an alien entity that takes possession of a woman and begins tearing the station apart, piece by piece, throwing destructive energy blasts. Bud fights the powerful alien every inch of the way, but is reluctant to harm the possessed woman . . . until he falls. To prevent the dangerous alien from leaving the station, the crew must evacuate everyone and prepare for the self destruction of the Nelson Mandela. Can a heartbroken Dr. Grace Lord save the day?
