The year is 2110. Humankind is entering a new golden age.But when an amateur astronomer points his telescope at just the right corner of the night sky, he sees disaster hurtling toward Earth: a chunk of rock that could annihilate civilization. While a few fanatics welcome the apocalyptic destruction as a sign from God, the greatest scientific minds of Earth desperately search for a way to avoid the inevitable. On board the starship Goliath, Captain Robert Singh and his crew must race against time to redirect the meteor from its deadly collision course. Suddenly they find themselves on the most important mission in human history - a mission whose success may require the ultimate sacrifice.
