While working as a visiting vet, Chris meets Misty, a border collie who's had a run-in with a hedge trimmer. Can he repair her nose? Then, Dr. Andrew Marchevsky takes on the case of Mei Mei, a rescued stray with her kneecaps in the wrong place. And, back at his own clinic, Chris races against the clock to help a cat that's fallen from a 30-foot-high window.
