This came to me in a dream, lol.
So we once again follow the adventures of our favourite red headed Alice. This time, she is a high level flautist on her way to an international music festival in France(?). (She's flying in from the states). But due to a terrible snowstorm, her plane was forced to land and she found herself stranded in London with nothing but her luggage and instrument.
Along the way, things happen. She doesn't have money in the right currency and has to sort that out. She eventually finds other musicians who have also been stranded and they have a holiday jam session in a public place, and then Alice realizes the true meaning of music and friendship and other cheesy things. Fun times.
