The trailer for The Ambushers.
When a government-built flying saucer is hijacked mid-flight by Jose Ortega, the exiled ruler for an outlaw nation, secret agent Matt Helm and the ship's former pilot Sheila Sommars are sent to recover it. Along the way they must deal with Ortega's henchmen, Francesca Madeiros (an operative for Helm's main nemesis Big O), who poses as a model and seduces Helm, and an assassin named Nassim.
