The Man Who Knew Too Much

Dr. Ben and Joe McKenna, simple, unsuspecting tourists, go on holiday to Morocco. With their son Hank with them, they are enjoying their vacation when they meet Mr. and Mrs. Drayton, an English couple, and a suspicious but friendly Frenchman, Louis Bernard. Later, as Ben and Joe are walking through the bazaar, an Arab runs up to them with a knife in his back. Ben literally catches the falling Arab and, to his horror, learns that it is Louis Bernard in disguise. The Frenchman manages to whisper something to Ben, and he finds himself drawn into the very center of an international conspiracy, the participants of which set as their goal an assassination attempt on a high-ranking person; only Ben can stop the course of events.
