Query-SPOILER!
I have just watched this film for the first time and thought it was great-however,there is something I am not sure on. What exactly happened during the operation to cause the mother to turn into murderer? I have watched the scene near the end a few times and can't work out what happened! Also,why did she kill her husband when he wasn't anything to do with this operation that went wrong? Many thanks!
