In this episode the phobias are sheep, moths and sausage dogs, again. On the surface, harmless animals. But for the patients checking into The Fear Clinic, they inspire pure terror. Eighteen-year-old Miriam has had a phobia of sheep ever since one charged at her while she was out on a walk with friends. Working in a factory 30 years ago led Dave to suffer blind panic whenever he sees a moth. After Devereaux's first treatment for his fear of sausage dogs didn't work, he undergoes a second round of therapy. Clinician Vivian must figure out why the initial treatment failed, and try to see what to do differently.

Jack has inherited an intense phobia of spiders from his mum. In order for treatment to be successful, clinician Emma needs to encourage Jack to confront a live spider. Dublin-born James has suffered from an intense fear of clowns since he was a young child, but after a life-changing few years which have shown James his true strength, this phobia feels like the only remaining thing in his life that he needs to combat. Mother-of-one Lynsey has had a phobia of fish ever since she choked on a fish bone as a child and worries about passing her phobia down to her son. Can the clinic help?
