Plot Synopsis

When a massive comet collides with the Sun, the explosion jettisons the planet Mercury from its orbit and sends it on a fatal collision course with Earth. With each passing day, Earth's unstable gravitational field creates catastrophic disasters that threaten to tear the planet apart. The only hope for survival is a 20-year-old hidden top-secret military weapon that has the power to destroy Mercury before it slams into Earth. The discredited scientist who invented the weapon races to activate the weapon before the rogue planet's influence destroys the Earth. Along with his team and an astronaut, he embarks on an adventure that takes them from the back roads of California to the vast reaches of space.
