A freelance photographer (Robert Stack) ends up in possession of a medallion that provides a key to hidden treasure, and others (most notably crooks led by Nancy Kwan) are after it. And can the photographer trust the purported widow (Elke Sommer) of the man who entrusted him with the item? Stack’s protagonist is effective in the fights but less than charming, but Sommer and Kwan add some interest in a fairly fast-moving tale, also known as The Corrupt Ones and originally titled Die Hölle von Macao.

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

Movie 540 for 2021.
