Unclaimed documents the efforts of a Vietnam veteran and Christian missionary named Tom Faunce to establish the truth of the man's origin, and to persuade the U.S. Joint Personnel Recovery Agency, a notoriously mismanaged bureaucracy, to assist in his identification. While also recounting Faunce's own troubled childhood and his difficult readjustment to civilian life after his service in Vietnam, Unclaimed makes a pretty strong argument that Robertson, a medic assigned to the clandestine MACV-SOG unit that made illegal incursions into Cambodia, survived a helicopter crash in Laos and five years of imprisonment by the Vietcong.
But it's also a nakedly manipulative film, intercutting missionary Faunce's history with shots of a ludicrously glum and silent family dinner, and indulging in some treacly sad-face piano music. Faunce and his family are 100 percent bullshit-free, but the film still can't stop fumbling with your emotional bra straps. And also with basic English composition, judging by one caption card's egregious dangling modifier. But the man who might be Robertson is both the point and the best part of the film. He comes across as sincere, his childlike vulnerability and the depiction of his life in Vietnam demanding sympathy.
