In 1969, Larry Hillblom founded his global courier company DHL. In 1995, the entrepreneur vanished in a plane crash off his Micronesian island home, leaving his billion-dollar estate to a university -- or so he thought. Directed by Alexis Manya Spraic, this engaging documentary tells Hillblom's story through the legal battle that ensued when would-be heirs began popping up all over the place to lay claim to the billionaire's bucks.
