Vicissitudes (2014)

William Carter Baily, the most successful man in the world, flies his old high school buddy, Lucas Daniel Parker, all the way out to Dubrovnik, Croatia from New York, USA. Lucas assumes it to be a casual, friendly gesture, and accepts, only to find out that in reality, Will is asking him to run a huge mission. Lucas, having given up running missions, is reluctant, but ultimately obliges to help Will. As Will and Lucas go about running this mission, they reminisce and catch up with each other, until things suddenly take a turn for the worst.
