Invasion Usa: Border War

When a Mexican gang hijacks a school bus full of American school girls, a Vietnam vet takes matters into his own deadly hands in this border thriller.

The gang of kidnappers is led by the ruthless crime lord Alphonso Guerrerro, whose daughter is on that bus. His ex-wife took his daughter back to the States, but Alphonso wants her back—and will stop at nothing to get her. Now he's got a devil's bounty of young women to be used as hostages, or sold into the horrors of slavery if his demands are not met.
But Vietnam vet Tom Brannon has something to say about this. His niece is on that school bus, so he's recruiting a battle-tough squad of ex-soldiers made up from the families of the kidnapped girls. They're going to rescue the girls and destroy Guerrerro and his gang of border thugs once and for all.
