"The crack Israeli Secret Service vs the International sky terrorists." "Assignment: Destruction to X19. On the edge of an oil-rich desert, Black September has established X19, a secret base where the art of sky sabotage is taught to paramilitary terror troops. While it operates, no plane can fly anywhere in the world free of fear. But Israel's Security Branch has other ideas. Their daredevil team of counterspy commandos has launched an operation that will smash X10 bullet by bullet, gun by gun, terrorist by terrorist."
