In India, an estimated 79% of women have experienced sexual harassment in public, but it’s hoped that a $1 million competition will reduce that figure. We visit Mumbai for the grand final of the Women's Safety XPRIZE, where five teams compete to win $1 million for designing a wearable gadget that will secretly alert others in the event of an attack. We follow the competitors through a series of challenges as they try to prove their device is the best - from buses winding their way through the heart of the city, to a grand convention centre where they have to convince members of the public that their invention can keep women and girls safe from harm.
