This movie is a hotchpotch affair right from the word go. It revolves around Angel Cafe (I guess they put in the 'blue' to indicate the genre of the movie). There is a waitress who looks like a stoned zombie, an inefficient looking detective who couldn't find his shoes if he lost them, and an anonymous character who tries to look mysterious, and keeps popping up throughout the movie at regular intervals (he is finally revealed to be the uncle of the waitress, who is keeping the tabs on his niece).
Then there are a couple of thugs who believe that there is a hidden cache of currency somewhere beneath the cafe. Apart from these characters, you have a bartender who is perpetually polishing glasses, and a teenage couple who are forever necking out at the cafe.
These characters keep moving around pointlessly, with contrived situations to accommodate lovemaking scenes, which have been censored in the clumsiest manner possible. Then there are additional sound tracks of moans, etc. when these scenes appear, which is really ridiculous because sometimes these sounds accompany chaste kisses too (not that there are many chaste kisses in the film).
The director realizes halfway through that the movie is dying on him, and puts in a murder to sustain the audience's interest. Not that it helps much. Finally the movie ends in a really stupid manner with the murder turning out to be an accident... oops! I revealed the suspense factor.
Hopeless performances and shoddy editing are other highlights of this amazing movie. The last scene where all those idiotic looking characters assemble for a photograph is sure to haunt you for weeks on end. My sincere advice... stay away!
