American Colonel Frank Harder, who came to France to work with parliament member Albert Lamar, actually turns out to be... the parliamentarian's wife, Marie-Louise, who disappeared eighteen years ago. From this moment on, life in a decent society begins to resemble a madhouse: preoccupied with finding his mother, Louis constantly puts forward the most fantastic versions of his birth - one more absurd than the other. The beautiful Jasant, flirting with Frank, was just six months ago... Gustav, and Matilda has no choice but to dance every now and then with “familiar strangers” and try to understand the simplest human relationships - friendship, loyalty, love... The moral of the funny French story does not pretend to be a revelation, but is not devoid of common sense: no matter what happens in our life, rich in surprises, we should not give in to despondency.
