Venus and Jupiter fear that Mars is about to cause yet another interplanetary war, and decide to distract him with a battle of the sexes on Earth.
Venus selects Celine as her champion. Celine is of Venusian descent and working on Earth as a sex surrogate. Like every Venusian female, Celine can regenerate a virtual virginity until she gives her true virginity to the man she will love for the rest of her life.
Jove (aka Jupiter) chooses Keefe as his warrior. Keefe is of Jovian descent and, like every Jovian male, has a secret he will reveal only to the woman he will love for the rest of his life.
