Enter Driss (played by Omar Sy), a young and charismatic immigrant from Mali who is hired as Philippe's caregiver. Driss is from a tough neighborhood and has limited education, but he is determined to make a better life for himself and his family. Initially, Philippe and Driss seem like an unlikely pair, with different backgrounds, personalities, and values. However, as they spend more time together, they develop an extraordinary bond that transcends their social and cultural differences.

The film is based on the real-life friendship between Philippe Pozzo di Borgo, a wealthy quadriplegic, and Driss Bassiry, a young man from the projects who becomes his caregiver. Despite their vastly different backgrounds and personalities, the two form an unlikely bond that transcends their social and economic differences.

Driss encourages Philippe to pursue a romantic relationship with a woman he has been corresponding with by letter but was too afraid to meet due to his disability.
