For the better part of two decades Elise has been living a quiet domestic life, taking care of her husband and daughters. She can't remember the last time she was responsible for anything more than organizing a dinner party.

Days pass by in a daze for her until she gets a call from the hospital. With her husband involved in a car accident, Elise must step up and go to a conference in Portugal in his stead.

After years of suppressing her true character, Elise attends the conference and is a surprise hit. While there, she meets Sabine, a young PhD student to whom she's immediately drawn. After the conference, Sabine asks Elise to join her on a weekend trip to Porto. For the first time in a long time Elise makes an impulsive decision... and accepts.

Why did she do that? What was she thinking? And how is Sabine going to react if she ever finds out the truth?
