The storyline will follow Sophie Lowe, who stars as Alice, who returns from Wonderland to tell the other side of the world what is beyond the rabbit hole.

The description for "Once Upon a Time in Wonderland" episode 1 titled "Down the Rabbit Hole" is as follows: "As our story begins, Alice finds herself in an asylum and everything she believes is called into question."

However, her story sounds insane and doctors attempt to cure her with a treatment so she can forget everything that happened in Wonderland. But Alice is saved just in time by the White Rabbit (John Lithgow) and Knave of Hearts (Michael Socha). The three return to Wonderland, with Alice hoping to find her lost lover, the genie Cyrus (Peter Gadiot).

According to photos of episode 1 posted by ABC, Alice is questioned by a panel of doctors who are troubled by her tales of Wonderland. Further pictures show Cyrus and Alice together, and the genie has a very important question for her.
