Last in series following business expert Nick Hewer on his quest to help small farms diversify. This week Nick meets Jim and Martina Magill in Newry, Co. Down. The Magill's produce an equine flax oil high in omega-3, which they claim has many physical and health benefits for horses. They have big plans to expand their flax oil products into the human market but Nick is concerned they have taken on too much too soon. Can Nick persuade Jim to see things his way?
