Das Gift der Eifersucht

A happily married couple’s wedding anniversary is coming up. The husband plans a surprise, but his behavior makes it look as though he might have a mistress. His wife, consumed by jealousy, decides to leave him. Her parents hire a private detective agency to keep an eye on the husband, hoping to catch him red-handed with another woman. As it turns out, however, the husband had simply commissioned a new dress for his wife from a seamstress—a surprise for their wedding anniversary.
