The dying grandfather gives Mark an ultimatum: in order to receive the inheritance, he must get married within a month. Mark is not too happy about this prospect: he is still experiencing the death of his wife and is not ready for a new relationship. But he loves his grandfather too much and wants to brighten up his last days, so he finds, as it seems to him, the ideal candidate for the role of a fictitious wife - his secretary Lara. There is only one nuance - Lara is pregnant, and this child is not Mark’s.
