In the cold winter of the 1980s, there was heavy snowfall, and the young Lu Nian suffered a lot while living with relatives. Lei Lei, the meritorious military dog left behind by her father, always guarded her. Faced with others coveting the relics, she fled overnight with Lei Lei, who was full of pain, during the wind and snow. Lei Lei tried his best to protect his little master. One person and one dog went through hardships and dangers. Fortunately, they were rescued by a kind-hearted veteran. Both of them were seriously injured and fell into danger. It happened that Zhang Dajun returned from the army. The old photos collected by Lu Nian may help her find her father's former comrades. .
