Four men climb on stage during Elvis Presley’s show in Las Vegas, supposedly to shake his hand. Fearing for his life, Elvis and bassist Jerry Scheff immobilize the men using karate moves. No charges are filed, but later Elvis tells the audience, “I’m sorry, ladies and gentlemen. I’m sorry I didn’t break his goddamned neck, is what I’m sorry about.” After the attack, Elvis becomes convinced that his former karate instructor Mike Stone, the man now sleeping with his ex, Priscilla, is trying to have him killed.
