Bob's wife, Margaret, is attempting to throw a surprise birthday celebration for Bob while he is at work; she tells him that they are going to a restaurant when she calls him. Bob works as a dentist and is seemingly going through a mid-life crisis on his 40th birthday. The short film shows Bob staring at a young woman in the office while his wife is at home working on the surprise party. She has a closet full of decorations to make the celebration fun for everyone. One of Bob's patients goes on to tell him that he had read that dentists have the highest suicide rate of all professions and continues to ask about his hours and salary while Bob works on the patient's teeth.
The film continues at home when everyone arrives at Bob and Margaret's house for the party. As they await Bob's presence, Margaret watches the time and quickly checks the window to notice he is driving down the road and tells the guests to hide until she gives a signal for them to come out. When Bob arrives, he walks directly to the kitchen, disregarding Margaret, and then asks her if she is bothered that they never had children and questions whether he should leave his job as a dentist. The guests continue to hide while Bob changes. As he is changing he comes down the stairs bottomless and Margaret frantically tells him to put pants on. He takes this to offence and says that she used to love when he did that, furthering his mid-life crisis even more.
Bob continues speaking about how all of their friends, who are hiding behind couches and listening, are not really their friends and that they do not even like them. He goes on to say that Margaret should find another husband and becomes jealous. Bob yells up to Margaret, who is in the bedroom and upset over the disaster of a surprise party, and says that they should have children. He goes on to ask if she finds him attractive while she brings down pants and trousers for him. He goes outside to wait in the car because he still believes they are going out for dinner. Margaret follows him, knowing the party she had planned is now destroyed, and leaves all their friends she had invited behind.
