The story takes place on Christmas Eve. In the strong Christmas atmosphere, everyone temporarily puts down their work and enjoys the joy of reuniting with their families. George (Michel Blanc) seems to be the only emergency doctor still working in the city. He received an urgent call for help and rushed to the patient's home. On the way, a careless deliveryman Malik (Hakim Jemili) hit him on a bicycle. Although he was not injured, it triggered George's old illness-sciatica. In desperation, Malik had to take over George's position and became a temporary doctor to rush to the patient's home, while George told him how to treat the disease by phone on the spot. Can the treatment under remote control go smoothly this time?
