After a devastating pandemic wipes out civilization and his wife is killed, a special forces operative leaves his post and retreats to live in seclusion in the Nordic wilderness. Many years later, a woman, injured and on the run, arrives at his doorstep. She has fled from a laboratory, and those chasing her are convinced that her blood holds the secret to a global cure. Initially reluctant to intervene, the soldier’s reservations vanish when he learns that the person hunting her is Commander Stone, the very man responsible for his wife’s death years earlier.
