Third instalment of the successful 'Species' franchise. In the ongoing fight for supremacy between mankind and human/alien hybrids, a fatal hybrid weakness has given humans the advantage. Until now. When Sara (Sunny Mabrey), the daughter of Eve (Natasha Henstridge) is born, she grows into the most genetically perfect alien form yet. Seeking to repopulate her kind, this dangerously beautiful femme fatale heeds an overwhelming drive to mate, while a crack military team trails her in an attempt to end the war between the two species forever.
