As society teeters on the brink of nuclear apocalypse, Markus Moksha, an oversexed alcoholic anthropologist, encounters Dordogne, a telepathic woman from the future who recognizes his import to the fate of humanity. She recruits him to join her team of time-traveling scientists aboard their UFO, as they venture back through the distant past, seeking to enact a change that will bring peace to his time and avert the Great War.

Along the way, Markus discovers that his loathsome christian upbringing, together with an unabashed love of alcohol, drugs, and promiscuous sex, have inexplicably imbued him with the perfect set of tools for furthering the mission. However, mounting hardship and clashes for control of the timeline force every member of the team to look within and reflect on what it means to be human.

As civilization's last hope of avoiding Armageddon, they must persevere in the face of pervasive challenges and devastating loss, with the wish of returning home to find a new and brighter world, where the political and religious feuds of the troglodyte past have given way to an enlightened, Superhuman future.
