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, with Luc constantly at Thomas' side as he vainly struggles against the disease and confronts the indignity of treatment. As Thomas and Luc become closer, their new relationship begins to alienate their significant others, and Thomas' father cannot understand why his son doesn't fight against his illness with great vehemence.
