Krista is returning after three months of travelling in Southeast Asia. She has been profoundly affected by the experience, and is determined to make fundamental changes in her life -- a decision that will have important consequences for those closest to her. Meanwhile, Mel is taking stock of his life and wondering if it's time to hand the company reins to someone else and get back to his first love: flying. Bobby is finding himself drawn all the more closely to Petra and Connor, with shocking and unexpected consequences when his enemies attempt to follow through on their threat against his life. And there's the potential for new romance -- and new adventure -- in Blake's life, when police Constable Lindsay Gallagher transfers to Yellowknife.
