Aunt Zelda has a gift to give to Elmer from his Grandpa Eldo, but she can't remember what it is or where it is. Zelda's memory sometimes escapes her, and her hearing isn't what it used to be, so they set off together to find Grandpa Eldo and solve the mystery of the forgotten gift.

In his 30th storybook, Elmer's love, patience and respect for his Aunt Zelda and Grandpa Eldo makes for a heart-warming depiction of family life with elderly relatives, and deftly deals with themes relating to dementia with love and respect.
