Conventional wisdom - with a touch of joking undertone - suggests that the shortest fling can become the most significant one for a man; this is when it is unambiguously supported by a paternity test result. Of course, such a "literary work" is usually based on, albeit accidental, but ... Treason. So what should the heroes, husband and wife, mother and father with three children, do? Should they raise the concern, should they reveal the whole truth? But it can hurt deeply the one you love, even cause a breakup. So should they cover up the truth? Should they cover up it forever and would bear this burden for the rest of their lives? But it is not that easy to handle the pressure. Still, there is a way out, and the heroes of the film have found a solution - it turns out that they can do neither. It is enough just to love each other. Indeed, it seems that having such explosive characters our heroes won’t definitely be able to manage it without the help of this tool.
