Part-time worker Lin Xiaoman tries to stop dog thieves in her past life and is killed, unexpectedly time-traveling to become a nurse at a high-end pet hospital, and also gains the ability to understand dog language. She accurately heals the foot injury of Fudou, the Gu family's pampered pet, making a name for herself, resolves the nanny's constant troubles, and even calms all the restless famous dogs at the wealthy family's pet banquet, rising to become a sought-after pet master in the industry. When dog thieves break into the island team-building event, she teams up with Fudou to rescue all the stolen dogs, invests all the bounty into animal protection charities, and inspires more people to care about pet safety and stray animal rescue.
