Ecstasy has shaped fashion, music, and nightlife for three decades, and this film tracks two recreational users through a single night out while CGI sequences follow the drug's path through the bloodstream and into the brain. Toxicologists, neuroscientists, and pharmacologists narrate what MDMA actually does at the cellular level, correcting a few common myths about how the high builds and fades. The film also visits research at the University of Chicago into ecstasy's capacity to generate empathy, part of an ongoing case for its use as a therapy drug rather than a street one. Balancing that is the damage: a young woman who needed a liver transplant after using the drug, and a father describing how his 18-year-old daughter died after drinking too much water while on it, a reaction tied to the drug's effect on the body's fluid regulation. The film keeps the pleasure and the harm in the same frame, letting the biology explain both.
