Following the death of his wife, Wilbur Cartwright moves in with his son, John, who lives with his wife, Louisa, and their four-year-old son, David. The family gets along for a year, with Grampa especially enjoying spending time with his grandson; however, following the first year, Grampa requests to build a room in the cellar of John’s home, and John and Louisa secretly agree that he is showing his age.  Even so, Grampa and David befriend another grandfather and son at the park, and the grandfather, James Sheffield, ends up being the father of John’s boss at work, Duncan Sheffield. Grampa and David begin to spend time at the Sheffield home until Duncan calls John into his office at work to say that his wife has recently lost an expensive diamond ring and ask if John can ask his father whether or not he saw it in their home while visiting. John realizes Duncan has accused his father of stealing, but when he jokingly asks his father if he saw the ring, Grampa acts suspiciously and struggles to continue reading his magazine. John sneaks into his father’s room and looks through his belongings, first finding random pins and an earring his wife had lost months ago and then stumbling across a diamond ring in a bottom drawer. John becomes afraid, unsure of what to do.  The next day at work, John still doesn’t know what to do but finds himself telling Duncan that he was the one who took the ring when he visited the other night. Duncan does not appear angry and promotes John in four months. A few months later, Grampa dies, and John empties the drawer of pins into a lake.
