Oxygen (2010)

Professor Duhamel, a man of science with a cold heart, becomes deeply engrossed in the peculiar case of Lucas, a timid, well-behaved boy suffering from a rare, genetic lung disease. His father, Karl, cherishes Lucas, while his rebellious brother, Tom, chooses to live his life in the fast lane, exploring every fleeting pleasure with his questionable friend, Jimmy. Tragedy strikes when Lucas, the beacon of hope, succumbs during a promising transplant. Concurrently, Tom finds an unexpected kindred spirit in Xavier, an older man who shares his spot on the donor list. As the years roll by, Tom's life grows complicated with intense, ill-fated romances with two girls, one of whom is confined to a bubble due to a relentless infection. These tumultuous love stories not only disrupt their personal lives but also shake Tom's resolve to keep fighting for his life. Meanwhile, Jimmy, the loyal friend, goes to extreme lengths, leaving no stone unturned, and no casualty spared in his quest to improve Tom's chances of survival.
