Sinopsis
En víspera del 4 de julio, unas gigantescas naves espaciales aparecen en el cielo. El estupor inicial se convierte en terror al ver cómo éstas atacan al planeta lanzando rayos destructivos en las mayores ciudades de todo el mundo. Ahora la única esperanza para la salvación de la tierra está en la voluntad de algunos supervivientes, que se unen planeando el último ataque masivo contra los alienígenas, antes de que sea demasiado tarde para la humanidad.
