Passenger is a Polish film about a German ex-officer at a concentration camp who sees someone she believes to be an ex-inmate on board a cruise ship. From there, she recounts her experience during the war, and the odd dynamic she had with this one particular prisoner.
It only runs an hour long, and is very upfront about the fact it's an unfinished film, due to the director suddenly dying during production. The people who picked up the pieces and edited into what it is today try to work this into the film via a narration which adds some subtext, and tries to link what happened to the film to the themes of the film's story, to mixed results.
I guess an attempt at acknowledging the film's backstory and working it into the film was better than nothing, but it might strain a little in the closing narration (especially when the narrator also stops speaking mid-sentence, then the film ends).
But for what it is, it's still quite good. Might well have been even better had all the scenes been filmed, but there was certainly enough here for a compelling, semi-experimental hour-long film.
