A TV reporter and his assisstant go to a small Swiss village to do a programme with a reclusive scientist, an expert on world food shortages. During this time, an Italian immigrant worker is killed in a road crash and the reporter becomes involved in uncovering the truth about his death.
This romantic drama follows two policemen whose job is to investigate the lives of foreigners who have applied for Swiss citizenship. Among the applicants they must screen are a French psychiatrist and his wife, and a ballet dancer. The married couple are quickly accepted, but the dancer's life offers some objections. However, since the younger policeman has fallen in love with her, there is a chance that she, too, will win Swiss citizenship.
