When Ella and Jem meet, the physical resemblance is uncanny, but their lives couldn't be more different. One is from a tiny island in a deprived Northern community - pretty much the back of beyond - where she has no job, no boyfriend, limited prospects. The other is a London socialite, an aspiring actress living in a multi-million-pound mansion. By all appearances, she's living a charmed life, but she's got some serious sh*t to run away from. Both of them have. Can either hide in her double's skin? And at what cost? Will it solve any of the problems or merely compound them?
