Robbie, the master's baby, has been mysteriously beamed to Mars. It's up to our heroes plus a houseful of new friends - a fan, microwave, calculator, bag of cheddar-flavored popcorn and "the contraption in the junk drawer"- to reach for the stars and bring him safely home.

What are you all doing up here?
We're just hanging. Hanging and floating. It's a gas, man.
Yeah. Specifically, helium.
