For Sharyn Hildreth having MS has meant often needing to have a 'plan B'. Directing plays rather than acting in them has become her latest 'plan B'. Sharyn is one of 4000 New Zealanders who live with Multiple Sclerosis. It's a condition that affects the central nervous system and can result in disabilities, both visible and invisible. This week, One in Five is in Hawkes Bay to meet four people living their lives in the company of MS.
