After almost three years of having left to Zurich, Cristina returns to Seattle in hope of visiting her friends- perhaps seeking closure. So much has changed, yet so much remains the same. She faces herself with having to confront the traumas of her past- and the love of her life, Owen. The greatest test she'll face is whether she will stay in Zurich and give up the person she loves most, or return to Seattle for good, and forfeit the successful life full of accomplishments she has built away from her friends and loved ones.
