Clara has always lived in her head, occupying a secondary life while her own has fallen apart around her. At 35, she finds herself still temping in unsatisfying jobs while living in a shared house with five other girls. She knows her daydreaming is killing her chances to succeed in life so when an ad appears to join a support group, she pushes out of her comfort zone and signs up.

There she meets her people but she's not exactly sure she wants them to be her people: among them there's Jax, who lives a double life as a detective; Bob, who has an invisible family and Janice, who’s been married to Tom Cruise in her head for 30 years. Under the guidance of ex-daydreamer, Dr Hill, and his assistant Alice, they all attempt to free themselves from their fantasies and reconnect with the real world.

Clara is determined to cure herself from her addiction to relationships that only exist in her head but her recovery is threatened by her growing obsession with Dr Hill. Could he be the person to finally fix her?
