In the year 2071, humanity has colonized several of the planets and moons of the solar system leaving the now uninhabitable surface of planet Earth behind.

Thrown off course by the addition of new members that they meet in their travels—Ein, a genetically engineered, highly intelligent Welsh Corgi; femme fatale Faye Valentine, an enigmatic trickster with memory loss; and the strange computer whiz kid Edward Wong—the crew embarks on thrilling adventures that unravel each member's dark and mysterious past little by little.
