In the year 2347, when Old Earth is pronounced uninhabitable, the Clarks load their family dog Hobart onto an intergalactic ark called the Dogstar to be transported to New Earth. Unfortunately, the Dogstar never arrives. All the dogs from old Earth and two confused robot pilots, Zeke and Alice are lost. But the Clark kids (and Gran) are determined to find the Dogstar and bring those dogs home. Robotics entrepreneur Bob Santino is just as determined to stop them.
