context: At a port in the South of France, six months after they met, the romance between Joan Wilder (Kathleen Turner) and Jack Colton (Michael Douglas) has become rocky. While Joan is suffering from a case of writer's block and cannot finish her next romantic novel, Jack only wants to wander the seas aimlessly on his boat, the Angelina. Later that afternoon at a book signing engagement held by her publisher, Gloria (Holland Taylor), Joan meets a charming Arab ruler named Omar (Spiros FocÃ¡s). Omar confesses to be a fan and offers Joan the opportunity to write his biography. Joan leaves with Omar, despite Jack's disapproval. Jack runs into Ralph (Danny DeVito), the swindler from Jack's past in Colombia. Recently out of prison, Ralph tracks down Jack, wanting to retrieve the stone Jack had stolen. An Arab named Tarak (Paul David Magid), tells Jack of Omar's true intentions and that he has the "Jewel of the Nile". Suddenly, the Angelina explodes, having been sabotaged under Omar's orders. Ralph and Jack team up to find not only Joan but also the fabled jewel.
  Omar wanted Joan to come with him so she will write a flattering account of his rule in Kadir. During her stay at his palace, she discovers that Omar is a brutal dictator, not the enlightened ruler who will unite the Arab world. In the palace jail, Joan meets Al-Julhara (Avner Eisenberg), a holy man who Omar fears. [Note 1] Learning that the prisoner is really the "Jewel of the Nile", Joan offers to take Al-Julhara to Kadir. The pair escape the palace, and with the help of Jack who hijacks Omar's F-16 fighter aircraft, are able to flee Omar's army into the desert. Ralph is left to fend for himself in the desert, captured by the rebel Sufi tribe led by Tarak, who has sworn to protect the Jewel so he can fulfill his people's destiny.
  Encountering a Nubian mountain African tribe, Jack is forced to battle for Joan's hand, with the son of the chief. Joan tells Jack, that the Jewel is Al-Julhara. At an upcoming festival in Kadir, Omar uses a smoke and mirror special effect created by an English rock &amp; roll technician (Daniel Peacock). Omar tries to convince onlookers that he is a prophet who will unite the Arab world. Jack, Joan and Al-Julhara arrive to unmask Omar as a fraud, but they are all captured. Omar sets up an elaborate and fiendish trap from The Savage Secret, Joan's most popular novel. Jack and Joan are suspended over a deep pit; the ropes holding up Jack are soaked with goat's blood and being rapidly chewed away by rats, while those supporting Joan are slowly being dissolved by drops of acid. Al-Julhara, however, is simply locked up in stocks. Ralph, along with Tarak and his Sufi followers who have come to rescue Al-Julhara, stumbles onto them and inadvertently saves them.
  As Omar takes center stage to address the Arab people, Jack and Joan disrupt the ceremony while Tarak and his Sufi followers battle Omar's guards below. A fire breaks out when part of Omar's platform apparatus crashes into the stage, engulfing it in flames. Jack and Joan are separated in the chaos and Omar corners her at the top of the burning scaffolding surrounding the stage. With help from Ralph, Jack rides a crane to the top of the scaffolding and knocks Omar over the side and down into the flames below. Once Omar dies, Al-Julhara rises as the real spiritual leader (fulfilling the prophecy by walking through fire unharmed).
  The following day, Jack and Joan are finally married by Al-Julhara. While he is genuinely happy for Jack and Joan, Ralph laments sadly that once again, he has nothing to show for his efforts. He is then acknowledged as being a true Sufi by Tarak, signified by being presented with a priceless jeweled dagger. Ralph is genuinely touched and happily accepts the gift. As Al-Julhara and his people, along with Ralph, Tarak, the Sufi and Gloria wave goodbye from the river's dock. Jack and Joan sail down the Nile.
