Among the guests are Dr. Pierre Gerrard and his companion Janine Du Bois that had an affair with Dr. Bonnet ten years ago in Italy. When they see each other, their love rekindle. However Dr. Bonnet has a dark secret since he is 104 years old and needs to have a gland transplanted every ten years to keep his youth. But his partner and friend Dr. Ludwig Weiss had a stroke in Switzerland and cannot perform the surgery.
