An amnesiac with vague memories of killing someone is brought back to England from Africa, where his arrival sets in motion a chain of unusual events and harrowing crimes. His intrepid nurse eagerly investigates in order to find out the truth, despite discouragement from the private detective she has hired, while her sister draws closer to the invalid, who is confined to a wheelchair but is concealing secrets of his own. This is a brisk little thriller with some twists that keep the viewer interested, even if the ending is a tad abrupt.

  Mildly recommended. Otto judiciously thinks this movie is OK, but not great.
