At a hospital in the Middle East a Jewish woman and one from Palestine both give birth to male infants. A scud attack is going on so the babies are put in a safe location in the hospital. Almost 18 years later the two mothers find out that they were given the wrong infant. That was picked up when the boy who assumed he was Jewish was being screened for national service.
That's the plot line of the foreign film "Le fils de l'autre." Of course, since the Jews and the Arabs are enemies, this discovery is shattering. Then everyone adjusts, even the fathers who took it the hardest. Nice theme that we are all really one human race.
However, if this film had been set in the U.S. the families would have been advised to sue the hospital. And they would have probably done just that. There would have been a large settlement. The hospital's public relations department would have issued a press release on how fail-safe procedures were introduced so that such an error would never happen again. Therefore, the film wouldn't have had such an inspirational resolution.
