Independence Day: Resurgence

Twenty years after the devastating alien invasion, the United Nations has set up the Earth Space Defense (ESD), a global defense and research program that reverse-engineers alien technology and serves as Earth's early warning system against extraterrestrial threats. Civilization has been restored and relative peace among nations exists following the human race's victory over the aliens' attacks.

As the twentieth anniversary of the invasion approaches, ESD Director David Levinson meets with warlord Dikembe Umbutu and Dr. Catherine Marceaux in the African state Republique Nationale d'Umbutu. They travel to an intact alien city destroyer and discover that alien survivors sent a distress call to their home world before their defeat. It is revealed that former U.S. President Thomas Whitmore, Dr. Brackish Okun, and Umbutu are telepathically linked to the aliens, following personal encounters, and have visions of an unidentified spherical object.
