Dana has just moved to California. She studies at university, plays the drums and her lifetime dream is to do music. And to get to the concert of her favorite rock band - "LA Angels". But there's a little trouble: her father thinks music is a waste of time. And the "Angels" disbanded about ten years ago. That's a tight corner. But it's not as hopeless as it might seem. Especially if your dad has been working at a time machine and you have access to his lab. One touch of a button - and Dana's moved 20 years back in time. The time when her favorite band is just starting their career. The only problem is that she fails to get back and her idols' life appears to be not as bright as she thought.
