After Tessie's grandmother, Lola, is diagnosed with dementia, Tessie makes it her mission to save Lola's memories. Tessie has created a machine that transports her inside Lola's mind — a majestic library. Every memory is a book, and Tessie is trying to save one very dear to her: a memory of her and her grandma singing karaoke.

Tessie and Lola can keep the memory if they recreate it perfectly. But thwarting their attempts at every turn is Mena, a small AI webcam. Mena is the dementia that's slowly creeping into Lola's mind. Will Tessie keep on trying in vain to save her grandmother's memories? Or learn to accept her grandmother's dementia?
