Dr. McKenna (Stewart), wife Day and son Hank are on vacation in Morocco when they meet the pleasant Louis Bernard.

But when Bernard is brutally stabbed in public, the dying man entrusts Dr. McKenna with information on a top secret assasination plot currently in the works.

The only problem is: someone's stolen Hank so as to ensure the couple's silence!

Can the McKennas get their boy back without harm coming to him, and uncover the mystery behind the upcoming high profile assassination?

Stalwart screen veteran Jimmy Stewart is a joy to watch per usual, but it's Miss Day's standout performance as tortured mother Jo McKenna that steals the show.

Best moment: Doris' shrieking scream during the cymbal-crash climax. It's a beautifully-staged moment of suspense and one of Hitch's finest setups.
