Cold Harvest

Two years after a comet strikes the earth, the population has dwindled, and disease has run rampant in a darkened, lawless world of violence. A bounty hunter named Roland is out to avenge the death of his brother. With the assistance of his sister-in-law, Christine, Roland must find one of the seven humans carrying the antibody to the deadly disease. Meanwhile, Little Ray is trying to kill off the seven in an attempt to rule the world. When Christine learns that she is pregnant and that the baby is likely to have the antibody gene, she becomes a target of Little Ray, who kidnaps her. Now, Roland must save her, the baby and perhaps the last hope for mankind. (official distributor synopsis)
