One woman in El Salvador is trying to say enough is enough when it comes to femicides, as the country has the worst rate in the world. Graciela Sagastume Lopez is the newly appointed special prosecutor against femicides and BBC 100 Women follows her in action trying to put a halt to the wave of murders that has made the country infamous. The film also hears from families of victims, international lawyers fighting for justice and reformed men trying to address male issues of identity and machismo - exploring why El Salvador consistently ranks number one in the world for women murdered by their intimate partner and what is being done about it.

It was a year that saw gender politics catapulted to the fore and many women across the world speaking out. In the two-part series, Trailblazers, the BBC 100 Women season spotlights the trailblazing women who have turned their feelings of anger and indignation into a moment of action. In this second episode the programme interviews Vicky Phelan, an Irish mother who exposed a cervical cancer scandal, and Park Soo-yeon who took on South Korea's spy cams. Plus in Peru, BBC 100 Women speaks to Cindy Arlette Contreras Bautista, who became the face of a campaign against domestic violence when a video of her being attacked by her boyfriend went viral.
