Meanwhile, his son, Sam was with friends in New York to attend an event. 

There they discover that it has been raining non-stop for the past 3 weeks, and after a series of weather related disasters that occurred over the world.

Everybody soon realizes that the world is going to enter a new ice age, as the rest of the world population tries to evacuate to the warm climates of the south.

Jack makes a daring attempt to rescue his son and his friends who are stuck in New York, who have to survive not only a massive wave, but freezing cold temperatures that could possibly kill them.
