As the Fourth of July nears, satellite engineer David Levinson (Jeff Goldblum) investigates a 3,000-mile-wide mother ship that’s approaching Earth. Fortunately, 20 years earlier, nations across the world started to use recovered extraterrestrial technology to develop an immense defense program. When the alien invaders attack with unprecedented force, the U.S. president, teams of scientists and brave fighter pilots, Dylan Hiller (Jessie T. Usher) and Jake Morrison (Liam Hemsworth), spring into action to save the planet from a seemingly invincible enemy.
In 1863, Mississippi farmer Newt Knight (Matthew McConaughey) serves as a medic for the Confederate Army. Opposed to slavery, Knight would rather help the wounded than fight the Union. After his nephew dies in battle, Newt returns home to Jones County to safeguard his family but is soon branded an outlaw deserter. Forced to flee, he finds refuge with a group of runaway slaves hiding out in the swamps. Forging an alliance with the slaves and other farmers, Knight leads a rebellion that would forever change history.
