Homer scoffs at the tea Lisa wants and demands the antacids. Lisa snaps at her father for belittling everything she believes in. To placate her, Homer takes her to a New Age store where they try out sensory deprivation tanks and each experience their own spiritual journey. Lisa sees herself from the perspective of figures in her life, eventually realizing that Homer loves her enough to take her to events that he does not personally like just to make her happy. Meanwhile, repo men take away the tank that Homer is in.
