Anne, now a middle-aged woman, is troubled by recent events in her life. When a long-hidden secret is discovered under the floorboards at Green Gables, Anne retreats into her memories to relive her troubled early years prior to arriving as an orphan at Green Gables and being adopted by the Cuthberts.

At the turn of the century on Prince Edward Island, Matthew Cuthbert and his sister Marilla decide to take on an orphan boy as help for their farm. But they get an unexpected jolt when they're mistakenly sent a girl instead: Anne Shirley.
