American teenager Ronnie Segal and her friend, Brenda, arrive in Jerusalem, Israel, on a school trip. Elsewhere in the city, Emil Saber visits his former colleague, Professor Herbert Walker, claiming the professor gave him a fake King Herod coin. Walker pleads his innocence, and mumbles about the horrible deaths suffered by six of the possessors of King Herod’s seven coins. Saber strangles Walker, demanding to know the whereabouts of the seventh coin. Before dying, Walker mutters the name, Fouad Zouabi. Meanwhile, local pickpocket Salim Zouabi steals Ronnie’s camera, but when he returns home and gives it to his starving grandfather, Fouad Zouabi, he finds that the case only contains her passport. American Israeli police officer Lisa tries to prove herself to her uncle, Captain Galil, who gave her the job. Although she has no experience, she secretly investigates the murder of Professor Walker. At Walker’s home, she finds the forged coin left behind by Saber. Elsewhere, Ronnie demands that Salim return her camera case and passport. Ronnie fights him when he refuses, and he compliments her martial skills. She is outraged when he offers to sell her possessions back to her for $100, but she agrees. Meanwhile, Lisa takes the coin to a dealer and learns that seven rare coins were made by King Herod. The shop owner warns that the coins are very dangerous, as six owners of the coins have died. In time, Saber visits Fouad and demands to know where the seventh coin is. While there, Saber sees Ronnie’s passport and assumes Fouad recruited the girl to transport the coin to America. After Saber’s thugs beat Fouad, he removes the coin from its hiding place in a brick wall and places it in Ronnie’s camera case. Salim returns as Fouad is taken away by ambulance. Through her research, Lisa learns that Professor Walker, Saber, and Fouad were on an archeological dig together many years before when they unearthed the seventh coin. Elsewhere, Ronnie meets Salim in the old city, and they are followed by Saber’s thugs. After a long chase, Ronnie and Salim hide in an underground passageway and become infatuated with each other. Saber bribes a local bartender to tell him where Salim might be hiding. When Ronnie finds the coin in her camera case, Salim realizes it is the valuable coin of legend his grandfather always spoke about. They hide at the home of a butcher and share a passionate kiss. Soon after, Saber tracks them to the butcher shop and holds Salim at gunpoint. Ronnie pretends to throw the coin to Saber, enabling her and Salim to escape into the marketplace, while Saber fires into the crowd. Salim is grazed by a bullet, but they continue running. Meanwhile, Lisa appeals to her uncle, Captain Galil, to pursue Saber for the professor’s murder. Saber chases the teens to the top of a wall and prepares to shoot them. Captain Galil fires from below, and Saber falls to his death. Lisa rushes to Saber’s side, and finds six of the seven King Herod coins lying near his body. Elsewhere, Salim kisses Ronnie, and she returns his grandfather’s coin. Captain Galil promotes Lisa to detective, and Ronnie is reunited with her classmates. Salim wanders off, and although Ronnie is unable to find him, the young lovers think fondly of their shared adventure.
