Action ending at Camp David with Marine 1 and president

When Russian neo-nationalists hijack Air Force One, the world's most secure and extraordinary aircraft, the President is faced with a nearly impossible decision to give in to terrorist demands or sacrifice not only the country's dignity, but the lives of his wife and daughter.

On her first assignment aboard Air Force One, a rookie Secret Service agent faces the ultimate test when terrorists hijack the plane, intent on derailing a pivotal energy deal. With the President's life on the line and a global crisis at stake, her bravery and skills are pushed to the limit in a relentless battle that could change the course of history.

When the president of Russia suddenly dies, a man whose politics are virtually unknown succeeds him. The change in political leaders sparks paranoia among American CIA officials, so CIA director Bill Cabot recruits a young analyst to supply insight and advice on the situation. Then the unthinkable happens: a nuclear bomb explodes in a U.S. city, and America is quick to blame the Russians.

We always knew they were coming back. Using recovered alien technology, the nations of Earth have collaborated on an immense defense program to protect the planet. But nothing can prepare us for the aliens’ advanced and unprecedented force. Only the ingenuity of a few brave men and women can bring our world back from the brink of extinction.

Strange phenomena surface around the globe. The skies ignite. Terror races through the world's major cities. As these extraordinary events unfold, it becomes increasingly clear that a force of incredible magnitude has arrived. Its mission: total annihilation over the Fourth of July weekend. The last hope to stop the destruction is an unlikely group of people united by fate and unimaginable circumstances.
