The Seed of Man1969

During a Post-Apocalyptic period in the near future the majority of the European population has been wiped out by some sort of undefined plague. Cino and Dora, a young couple, are rounded up by what constitutes the authorities on an isolated temporary base. They are examined and given antibiotics which will protect them for six months, told to pick out a deserted house to live in the area, and use that time to conceive a child.
