One odd night, half-brothers Wirt and Greg wander into the Unknown. This murky fantasyland is home to pumpkin-headed villagers, musical frogs, and a talking bluebird named Beatrice. With her help, they set out to find Adelaide, a benevolent woman who can help them home. But the malignant Beast is hot on their tail and full of plans for their immortal souls.

"Over the Garden Wall" recalls the greatest fairy tales with its mingled horror and loveliness. It also manages to tell an affecting story about brotherhood. Wirt and Greg are hugely different people, but as the series winds on, they learn to appreciate everything that brings them together. Fans of family stories, all things Halloween, and offbeat animation will love wandering the Unknown beside them.
