Looking for a film title... HELP!

Ive been trying to track down a film I saw late night on channel 4 back in the mid 90s. All I can remember is that it was a french film, a woman was the main character and I can only remember that she went from being in her apartment to being stuck in a big warehouse or factory type building (I think there were other strangers there too in the same predicament) and she was trying to get away from/avoid some sort of serial killer/murderer. The film was definitetly a comedy despite the murderer aspect, albeit a dark/black humour. I dont remember much gore so I dont know if it was a Red Triangle film, but I may be wrong on that. I just remember that it was a really enjoyable film but have no idea what it was called! Ive scoured the net looking at every french film through the 90s but no joy. Delicatessen fits the bill but its not the one.

Hope somebody here can help!
