The film begins with an American expatriate being told about his inheriting $200,000. However, shortly after this, an attempt is made on his life--so it's obvious that someone wants that money. When he books passage on a steamer, it seems that he's fallen into ANOTHER plot--and the crew mistakes him for someone else....someone they want to kill! Talk about bad luck! DANGEROUS PASSAGE is a pretty well-written film--with an interesting plot that could have been handled a lot better. The problem is that the film was made by Pine-Thomas Productions--a very low-budget independent company that had only been making films for a short time before this film. As a result, the acting is only adequate, at best, and the direction is limp. In fact, given better direction, the film really could have been something worth seeing. As is, it's just a time-passer and it's easy to see why this film passed into the public domain.
