The family is on a nature walk through Carls Dad Caverns, when Homer tries to get a piece from a stalactite. This results in the family falling through the cave floor and winds up with Homer getting stuck in the ceiling of one of the lower chambers of the cave. Marge, Bart and Maggie go off to find help, while Lisa stays behind and tells her father a story to pass the time. Her story involves running from a bighorn sheep and into Mr. Burns mansion. The pair evades the tenacious sheep by finding refuge in the mansions attic, where Mr. Burns tells her the story of how he came to work at Moes Tavern by losing a scavenger hunt with a rich Texan. While there he learned (and tells to Lisa) the tale of the Moes treasure. The stories within stories culminate in the fate of the treasure being determined in the cave.

The Simpsons focuses on a family of five. There is the father, Homer, a dull-witted, alcoholic, lazy, but lovable man. He often gets his family into crazy situations but always manages to fix things. The mother, Marge, is a stay at home mom who keeps the family together. She is the ideal wife and mother though she can be a little naive at times. She always does what she thinks is best for her family.
Next is Bart, the 10 year old boy who lives on playing pranks. He gets into a lot of trouble but is generally a good kid. Then there is the neglected middle child, Lisa. Lisa is the brain of the family and sometimes feels left out because of that. She is an outcast at school because of her talent. Finally there is Maggie the baby. Though she doesn't say much she is well known especially for her red pacifier.
