The aliens are forcing the humans into a breeding program so they can create a slave army. Mark is given a chance to fight for his wife to prove the value of his seed, but he fails and Samantha is assigned to another.
She hates it, but slowly the aliens begin to attempt to reprogram her mind. Mark refuses to breed with anyone else and resists the aliens, so he is designated to be turned into a cuckold attendant for the women of the human race.
