David Suchet stars as Belgian detective Hercule Poirot in this adaptation of Agatha Christie's novel, which finds the prim-and-proper sleuth investigating the stabbing death of cruel-hearted Lady Boynton (Cheryl Campbell) at an archaeological expedition in Syria. But the deeper Poirot digs for clues, the more motives for murder he unearths. Among the slate of suspects is Lady Boynton's eccentric spouse (Tim Curry).
