This moving film is about people helping people, in this case using the radio. The story starts when a fishing boat on the North Sea has all its crew getting ill with an unknown disease. Through a radio amateur a message is sent and received by someone in Togo who gets in contact with the local doctor who gets to the conclusion that they had food poisoning caused by ham. The only person on the boat who is well is Mohamed who did not eat the spoiled ham because of his religion. A message is sent to Paris where they find the antidote, but the problem now is sending it to the boat. The only way is to parachute it. There is a cooperation between a German, an American, a Polish air hostess, the Russian Air Force, and a Danish plane to get the medicine to the boat. A film not to be missed, it takes its title from a poem (song?) by Paul Fort that says that if all the men and women in the world would hold hands, happiness would be for tomorrow. John Lennon had the same idea in his song Imagine.
