Matthias Duval, a publisher of greeting cards, is an unparalleled shark. But he is also totally overindebted. On the Riviera, he meets the beautiful twins Betty and Liz Kerner. They come from a rich family and have been promised an inheritance worth millions. The only obstacle is that they have to be married to receive the money. Duval has a great idea: he invents his own twin brother named Matthieu and in this way makes a pass at both ladies at the same time. It goes without saying that this cannot go well for long, and so Duval confuses not only those around him, but also himself, because soon he himself no longer knows who he actually is.
