It's the 4th of July, and America is celebrating. But when a hostile force attacks from both outer space and within Earth itself, our planet may be on the menu for a holiday barbecue. Can a small-town fireman (Ryan Merriman of "Pretty Little Liars"), a physics-loving teen (Andrea Brooks of "Supernatural"), a rogue scientist (Emily Holmes of METEOR STORM), a pair of nerd hackers and the stranded President Of The United States (Tom Everett Scott of THAT THING YOU DO!) now find a way to stop the invasion, nuke the alien mothership, and set off the biggest fireworks display of all? Keenan Tracy ("Bates Motel") co-stars in this Syfy Original hit from the producers of 12 DISASTERS and END OF THE WORLD.
