The usually dyspeptic and parsimonious Edgar undergoes a personality change when a perfect storm of circumstances and coincidences combine to convince him that wife Vivian is pregnant and about to give birth. In actuality two members of Vivian's family, Joe and Emma, are coming as house guests, and it is their baby that Edgar unknowingly is preparing a new nursery for. Edgar ultimately discovers the truth but not before he humorously interacts with other expectant fathers and decorators.
