Big waves help this female surfer overcome her biggest fears

Like many extreme sports, big wave surfing is male-dominated. Portuguese surfer Joana Andrade is one of a handful of women trying to change that, and the documentary "Big vs. Small" follows her in her endeavor. Stephanie Sy gives us a look inside the world of elite big wave surfers — and Andrade's ambitions and fears. It's part of our arts and culture series, CANVAS.
