What do you do when someone takes advantage of your greatest weakness? When Laura wakes up after her office Christmas party and sees a man's shirt on the floor, she is horrified. But this is no ordinary one-night-stand regret. Laura suffers from severe face-blindness, a condition that means she is completely unable to identify and remember faces. So the man she spent all night dancing with and kissing -- the man she thought she'd brought home -- was 'Pink Shirt'. But the shirt on her floor is blue. And now Laura must go to work every day, and face the man who took advantage of her condition. The man she has no way of recognising. She doesn't know who he is ... but she'll make him pay.
