The Kirkland's are a well-to-do middle class family. We are introduced to each member by means of dollar values and costs: salaries, education, food, etc. The numbers are overlaid on the frame for each family member.
Preoccupations with money are voiced as the family prepares for dinner. Meanwhile, the ceiling is coming apart. Bits and pieces, a tail of dirt, dropping from above. More dollar costs are presented, this time to fix the ceiling.
The youngest boy, a teenager, seems fed up with what is going on around him. He sets to do something about it, fifteen minutes from now. Why they are the last fifteen will be clear if you see this so-so short.
