Dead Ringer

The idea is simple, vain, exciting. Tap the app, upload a picture, find your #deadringer - and if you like, set up a meeting in real life.

When Ella and Jem connect, the resemblance is uncanny, but their lives are polar opposites.

One is stuck in a rut in her Northern hometown, while the other, an aspiring actor living in a multimillion-pound mansion, is a Chelsea socialite who knows she's skating on thin ice.

Other than their looks, their only similarity is the desire to escape.

Is it possible to hide in your double's skin? And at what cost? All too believable, twisty, compelling and fast - Dead Ringer will leave you reeling.
