In 1881, in Algeria, Michael Denning and Hector Servadac are fighting a duel when a comet brushing Earth takes the two men to the Moon where they discover a prehistoric civilization.

Algeria 1881. Two men, Michael Denning and Hector Servadac are having a duel with one another when a comet goes past the earth at low altitude. The strong wind this creates transports the two men to the moon. They find themselves in a jungle inhabited by reptiles and prehistoric humans. They have a difficult time before they manage to adapt to the dangers, but eventually they each find a girl to spend time with, awaiting the next return of the comet to take them back to Earth.—Mattias Thuresson

In 1881, Michael Denning, an American soldier, and Hector Servadac, a French aristocrat, are about to have a duel over a woman that they both are infatuated with. However, just as the two men are about to shoot at each other, a comet strikes the Earth and the gravitational pull draws in the two men. Michael and Hector soon deduce that this comet has been periodically landing on Earth and gathering people and animals from various eras in time, including people and dinosaurs. The two men then decide to put their differences aside and fight for survival as well as help make peace between two warring tribes of cavemen.—Brian Washington <[email protected]>
