Gortimer Gibbon's Life on Normal Street (2014)

S01E04 Gortimer and the Mystical Mind Eraser

Gortimer stumbles upon a secret he wishes he could un-know, and the weight of it follows him everywhere. Desperate to shake the memory, he turns to an oddly upbeat neighbor on Normal Street whose cheerful demeanor is matched only by her total inability to recall anything for more than a few minutes. Her sunny forgetfulness might be just the remedy—or it might lead him somewhere entirely unexpected.
