The Man Who Knew Too Much

“A little knowledge can be a deadly thing!”

On vacation in Morocco, the American doctor Ben McKenna (James Stewart) and his wife Jo (Doris Day), a former singing star, watch a man die in a crowded marketplace. Alfred Hitchcock puts them in a stranger's plot when their young son is kidnapped, and nobody they meet will say what they know. Ben and Jo are an ordinary couple carrying information they never asked for, and the danger comes from having it.
