I don't particularly like slasher films, but the best part about them is that they are easy to follow. A bunch of pretty ladies are being slashed to death by an unknown killer. A witness to one of these crimes decides to do some amateur sleuthing after witnessing an attack. The local police are totally cool with this. Although he greatly puts his own life and his girlfriend's life in danger, he eventually discovers the identity of the killer. Everyone is confused as to why this particular character is a murderer. Don't worry; there is a psychologist on hand to explain everything.
What the film lacks in plot, it makes up for in beauty. The witness is trapped between the glass doors in front of a beautiful white gallery. Everyone's house is nice, even the weather is perfect. They even find the killer's apartment in broad daylight. And, everything is so clean in this movie.
So, why is the movie called The Bird with the Crystal Plumage? It's because the killer's apartment is near a zoo, specifically where a specific bird is housed. It is supposedly a rare bird from Siberia. That's just a bit of cheeky humor. It's actually a Crowned Crane from Africa. Now, you may be wondering how I know that. It's because we have a Crowned Crane as part of the area where I work. His name is Frasier!
