A deluxe version of Agatha Christie's favourite mystery story, published in 1937, and a thematic follow-up to her Murder on the Orient Express. Set aboard a steamship cruising down the Nile, an extremely unpopular heiress is murdered and everyone on the ship is suspect. The passengers include the eminent detective Hercule Poirot (Ustinov), who cuts short his vacation in order to solve the mystery. The cast features the cream of '70s Hollywood and even includes classic-era stars Davis and Niven.
