In the city of Parish, the Major Ben Marshall lives with his autistic brother Terry, his son Leo, his daughter Samantha and his second wife Lynne. When a comet changes its route and collides on Earth, the scientists discover that an anomaly is the cause and they bring two geniuses to join their team in the research. They find that the anomaly is a gravitational vacuum indeed and mankind is doomed to annihilation. But Terry convinces his brother Ben to drive him to Houston to save the planet.—Claudio Carvalho, Rio de Janeiro, Brazil
