The story of Daniel continues here: the boy who loves cats but is very allergic to their fur, and who had a bionic cat built for him by his neighbor and engineer, Professor George. Boing-Boing is just like a real cat, but with fiber-optic fur, computer-controlled joints, electronic eyes, and ceramic-sensor whiskers. In this fifth installment to the series, Boing-Boing and Daniel defy gravity to take on an adventure in space, where they must save the Space Station from falling to earth.
