This program is part of a PBS series that explores the nature of sex in all species, from plants to humans. In this episode, the subject is the sex contract. After the male has won his mate through his courtship overtures, the process continues. Offspring are on the way, but in the meantime, what is the nature of this relationship? Is it monogamous, or does the male have a roving eye? The program looks at the habits of different species, from the crane and wolf, who mate for life, to the philandering ways of the primates, including -- sometimes -- man.
