Advertising was already booming in 1933. Rohr, a Berlin soapmaker, was looking for a particularly attractive face to promote his new product. And he finds it in a shot by photojournalist Schmidt, but the problem is that Mr Schmidt has no idea where, when or who he took the photo of. So a private detective agency and the "culprit" himself, the photographer, who is, for understandable reasons, a little "forgetful", start investigating the beautiful lady.
