Young Tammas Milton needs an operation. The doctor wants to use chloroform but the locals in the Glen are against this new idea. The doctor proves its worth by using it to put lassie to sleep for over twenty minutes. After operating in his own house to save the young mans life, the elderly doctor in payment has extracted a promise from his father, a friend who was the previous owner of Lassie, that he will allow him to send the young man on a four year medical course in Edinburgh so he can take over from him one day as doctor in the Glen.The young man when recovered is sent away and the increasingly old doctor continues administering to his patients in the area, who begin to fear for his health. One snowy night the doctor is called out and sees a patient. On the way home, he dozes off on his horse no cars and a tree branch knocks him down into the snow. Lassie rushes across a damaged bridge over a flood swollen river to get help and when he returns with two men, the bridge has been washed away. ........
