Following the events of Season 4, Finn (voice of Jeremy Shada) and Jake (John DiMaggio) find a way to undo the latest havoc the Lich (Ron Perlman) wreaked in their lives.

Princess Bubblegum (Hynden Walch), busy with her lab experiments and running Candy Kingdom, has no time for love despite Peppermint Butler's (Steve Little) best efforts to set her up. Ice King (Tom Kenny) writes fanfiction that Marceline (Olivia Olson) later hijacks. BMO (Niki Yang) erases a core system driver, and Lumpy Space Princess (Pendleton Ward) gets robbed.
