On April 1, 2014, Dutch friends Lisanne Froon and Kris Kremers set out to hike a popular trail in Boquete, Panama. The two friends were vacationing together in the small tourist town, finding adventures around Boquete until they would start their volunteering jobs at a local school. When the women didn't return from their hike on the El Pianista trail, a frantic search would uncover more mysteries than answers about what happened to the girls.
