In the Bellacorteza Forest, in the hollow of the oak tree where Archibald Fox runs his bookstore, any animal that wishes can leave the book they have written and trust that someday someone will buy it. Ever since his memories started to slip away, Ferdinand Mole has been desperately searching for the book he wrote compiling his memoirs, so he can remember what he did and who his loved ones were. There is only one copy, which he left at the bookstore years ago. But a mysterious customer has just bought it... With the help of old photographs, Archibald and Ferdinand follow his trail through the forest, on a journey where dreams, memories, and reality will intertwine.
