If something can go wrong, it can go dreadfully wrong.
I had to open the lips of the cassette in order to get the film out of there, I had previously pulled the leader in the cassette. While trying to pull the film out of it, I pulled something that happened to be one edge of the perforation of the film. Previously, the camera had "chewed" this edge edge by pulling it I totally ripped it. Needless to say the by now narrower film wouldn't fit the reel, it was too narrow. So I ended up just placing the film in the tank as is and hoping for the best... which didn't really come.
I knew I'd get parts of the film sticking together and prevent proper wetting of the emulsion, which happened for the most part of the film. There were few (2-3) shots that were more or less unaffected and revealed that it would be absolutely usable. Any colour distortion could be corrected. Some shots can be characterised as, eh... psychedelic and the rest were totally ruined.
