Overview:Jonnie Irwin takes up the challenge of helping a London couple with a big business idea find a rural home and enough land to live off in South Wales. Jonnie also lends a hand helping to save one of Wales's rarest species. (N.B. Due to one of the house hunters being a convicted sex offender, a fact he hid from the programme's production team and that only came to light once it had aired, this episode has never been broadcast again)
