Twisted

A young woman trying to escape unwanted male attention on a late night train, gladly accepts a generous offer from a kind female passenger. It is her first time in London, and she is glad to be given a lift and somewhere safe to stay for the night. When she arrives at the woman's house, she immediately senses that she has made a mistake. She makes up her mind that she will leave first thing in the morning. When she wakes up the next morning, and finds she is locked in, she is terrified, but she could never guess at the unimaginable events, which are about to overtake her.
