The Fountain of Youth

»Humphrey Baxter is a respected scientist, an expert in the peculiar field of human glands. When the aging rese­ar­cher falls for young theatre actress Carolyn Coates, everybody in New York – even Baxter – is surprised when the beautiful socialite, in turn, falls in love with him. After a three year absence in Vienna, where he has been conduc­ting secret research, Baxter returns to America to find that his woman has abandoned him for a handsome tennis player, Alan Brody. With extra­or­di­nary patience and restraint, the scientist draws together his painsta­king plans, to exact cold and damning revenge on the woman who has betrayed him.« (IMDb)
