Thomas has been estranged from his brother Luc for several years, due in part to his difficulties in dealing with Luc's homosexuality. But when Thomas is diagnosed with a rare blood disease, which is difficult to treat and impossible to cure, he decides he wants to bring Luc back into his life. The brothers soon become inseparable, and their new relationship begins to alienate their significant others.
Unfortunately the movie His Brother is not yet available on HBO Max.
