VACATION on MARS

Regulating Martian gravitation, atmosphere, and ocean-making technology has made the Red Planet an Earth-like tourist destination, and the Robinsons are rocket-bound for a Vacation on Mars, but an underwater earthquake rumbles the planet's crust and a tsunami crashes land, they must survive the tidal onslaught.

A colony of criminals sent to serve their sentences on Mars finds opportunity when a tsunami-induced avalanche jostles ice and snow from the treacherous mountain pass dividing desolate desert penitentiary and lush ocean paradise. The criminals stampede to sand, sun, and tourist terrorism, hounding the Robinsons in a near-fatal chase.

Slipping the diabolical snare, the Robinsons hunker down in a cruise ship washed ashore and snagged atop a grove of palm trees, prepared for full siege. Fifteen year-old computer whiz Rory Robinson hands the bandits their final coup, hacking the Martian gravitational system, treating the hellish horde to some unexpected anti-gravitational aerobatics, sending them trampolining skyward and ending their arch-villainous escapades with a ground-slamming finale,leaving the lecherous illegals to retreat to their desert denizen, the Robinsons relishing the remainder of their Vacation on Mars in joyous, uninterrupted ocean splendor.
