For floundering 34-year-old Ben Chambers the answer is obvious: find out where it came from and take it there to be fixed, even if it means risking his marriage in the process. Determined to achieve something for once in his life, Ben embarks on a journey that takes him and the endearing robot, Tang, to the far side of the globe...and back again. Together they will discover that friendship can rise up under the strangest circumstances, and that Artificial Intelligence can teach a man what it is to be human.
