Before the Beatles in Loverpool

Is the year 2020 and nothing really happens in US Arizona. So when Alma (who is a big Beatles fan) goes to visit her aunt in Liverpool to get away from home for A while, she didn't expect that a stormy day in Liverpool could lead to time traveling. When she wakes up in the year 1956! What does she do when there is no place to go, and don't know anyone there! Will she meet John, Paul and George there!? And if so will it change things for The Beatles in the future?
