Adapted from Jonathan Larson's stage musical, the semi-autobiographical work takes us inside the struggles of aspiring musical theater playwright and composer attempting to complete an 8 year project of a dystopian futuristic musical called Superbia before his thirtieth birthday. Pressured by needing to compose a crucial song to complete the musical as the workshop for its one and only performance begins, his girlfriend (Alexandra Shipp) needing an answer to a crucial relationship question, another of his friends hospitalized after becoming HIV Positive, and the daily struggles of working at the Moondance Diner and finding ways to pay his bills, a constant ticking reminds Jon that he's running out of time.
The film jumps between the performance of tick, tick... BOOM! on a stage, narrated by a self-deprecating Jon (Andrew Garfield) and providing context to the story, while flashing back to sequences of his life in further detail. The movie doesn't so much break the fourth wall as ignore it completely while the audience is swallowed into his story and willingly taken along for the ride.
