Because Gaetan Puccini accidentally kills himself while trying the latest model designed by "Cycles Puccini", Marcello, his nephew, succeeds him at the head of the firm. Very quickly, he ran into Michel Frémont, storekeeper and staff representative. This is because Marcello is much more learned in astrology than in business management and only makes his decisions by consulting the stars. Faced with these extravagances, Michel Frémont reacts, but the young CEO does not accept his ironic reproaches and dismisses the delegate. The factory is in turmoil. We declare a strike with occupation, we sequester Marcello. It is then that the latter learns that Michel Frémont was born on the same day as him, so that they are linked by the stars. He quickly reinstated him and even appointed him technical director. However, he will not be able to prevent an accident which sends Michel to the hospital. Michel and himself: are they not linked by the stars.
