We all know someone like Becca.

She has the job everyone wants, a designer wardrobe, a hot-shot lawyer boyfriend, holidays to exotic locations. And she flaunts her perfect life all over social media.

It drove her colleague Lizzie mad, but she couldn't stop looking. They were never really friends - and yet Lizzie knew everything about her.

Or did she?

When chance, and a terrible mistake, pulls Lizzie back into Becca's orbit years after they lost touch, she'll realise that you can't always believe what you see online... and that finding out the truth might be the worst thing you can do.

There's no such thing as a perfect life. Only a perfect lie.
