Serge (Wim Willaert) and his four colleagues are employees of a small company that has been taken over by a large corporation. As a welcome gift in the new company, the new employer thought of a nice gesture and invited everyone to a thermal bath for a weekend, where they can get to know him and the new company better in a relaxed atmosphere. It's just stupid that her visit falls on the nudist day of the thermal baths.
After initial hesitation, everyone joins in... more or less enthusiastically....
