Independence Day

On July 2, 1996, an enormous alien mothership arrives in the orbit of the Earth and deploys multiple saucers, each 15 miles (24 kilometers) wide that take positions over Earth's major cities. U.S. Marine Captain Steven Hiller is deployed despite being on leave; his girlfriend, Jasmine Dubrow, worried about the aliens, decides to flee Los Angeles with her son, Dylan. In New York City, David Levinson, an MIT-trained satellite technician, decodes a signal embedded within global satellite transmissions, realizing it is the aliens' countdown timer for a coordinated attack. With help from his ex-wife, White House Communications Director Constance Spano, David and his father Julius gain access to the Oval Office and alert President Thomas Whitmore to the threat.
