Earth was going about its collective business when suddenly, just beyond its moon, a wormhole - controlled for ages by a tyrannical alien race called the Srasec - opened, ripping open the fabric of space. Within days, the Srasec had completely taken control of the Earth and all of her inhabitants. Landing in the Atlantic Ocean with their six-mile diameter spacecraft/coliseum, the Srasec began to round up inhabitants of Earth. Both humans and animals are used in life-and-death contests with other captives from alien worlds scattered across the universe. Video images of the games are sent back to the Srasec's home planet, where at home the Srasec placed bets on their favorite contestant. Earth people do not give up easily, thanks to the efforts of three men from Texas, who successfully changed the mind of the commander and astronauts of Earth's space station to take the offensive with a new and powerful weapon. With an untested weapon and spacecraft inferior to the aliens', the Earth's future rests in the hands of a handful of brave astronauts.
