Nathan is a young man who joins an AIDS activist group in 1990s Paris. As he attends the weekly meetings, he learns that some members prefer a more radical approach to their protests.
In Paris in the early 1990s, a group of activists goes to battle for those stricken with HIV/AIDS, taking on sluggish government agencies and major pharmaceutical companies in bold, invasive actions. The organization is ACT UP, and its members, many of them gay and HIV-positive, embrace their mission with a literal life-or-death urgency. Amid rallies, protests, fierce debates and ecstatic dance parties, the newcomer Nathan falls in love with Sean, the group’s radical firebrand, and their passion sparks against the shadow of mortality as the activists fight for a breakthrough.
