Overview: The Season 27 premiere features Jason DaSilva's "When I Walk," in which the filmmaker chronicles his life for five years after being diagnosed with multiple sclerosis at age 25. By happenstance, a family member records the moment when the diagnosis hits home: while vacationing in the Caribbean, his legs give out. Yet, not all is bad: he meets Alice Cook, whose mother also has MS, at a support group. The two fall in love, marry and collaborate on completing the documentary.
