Sarah is doing just fine.

Sure, she's been single for the last five years, and has to spend an uncomfortable amount of time around her ex-boyfriend, his perfect new girlfriend and all their mutual friends.

And yes, her job as a PA to one of the most disgusting men in London is mind-numbingly tedious and her career is a constant disappointment to her mother. But it's really okay. She's happy (ish).

So it's not surprising that when Sarah starts dreaming about a handsome stranger, she begins to look forward to falling asleep every night. Reality isn't nearly as exciting. That is until her dream-stranger makes an unexpected real-life appearance, leaving Sarah questioning everything she thought she wanted.

Because no one ever really finds the person of their dreams . . . do they?
