They may be twins, but Lizzie and Penny Berry are complete opposites. Penny is the life of the party—loud and outrageous, while quiet and thoughtful Lizzy is often left out of the crowd. The one trait they do share is a longing to do something spectacular with their lives, and as far as these two are concerned, there’s no better place to make their dreams come true than London. 
Presented with a once-in-a-lifetime house-sit at their grandmother’s home in a very desirable London neighborhood, it finally seems like Lizzie and Penny are a step closer to the exciting cosmopolitan life they’ve always wanted. But the more time they spend in the big city, they quickly discover it’s nothing like they expected. They may have to dream new dreams…but are they up to the challenge?
