Plot

The film follows Kim Mi-Ra (played by Choi Ji-Woo), a working mother and software engineer whose life changes when her son, Jung Dong-Myeong (Ko Dong-Ha), is diagnosed with Type 1 diabetes. Faced with the reality of lifelong insulin dependency and her son's distress regarding blood collection, Mi-Ra utilizes her technical background to source continuous glucose monitors (CGMs) from abroad, as they were not readily available in the local market at the time.

As she begins assisting other parents in the Type 1 diabetes community by importing and setting up these devices, Mi-Ra faces legal challenges, including accusations of importing unauthorized medical equipment without proper customs clearance or tax compliance.
