On the day of his first fight since leaving prison, former middleweight champion and weathered boxer, "Irish Mike" Flannigan, prepares for his highly anticipated return to the ring, a huge long-shot undercard at the legendary Madison Square Garden. But before he can face off against a new champion, he first needs to face the demons from his past, embarking on a redemptive emotional journey of second chances, self-sacrifice and forgiveness. From the producer of The Irishman and Joker, Day of the Fight marks a bold filmmaking debut from acclaimed actor turned writer-director Jack Huston (Boardwalk Empire, House of Gucci), starring Michael C. Pitt (Seven Psychopaths, The Dreamers), in a fearless lead performance, with knockout support from Nicolette Robinson (Woman of the Hour), John Magaro (Past Lives), Emmy and Golden Globe winner Steve Buscemi (Boardwalk Empire, Fargo), Golden Globe winner Ron Perlman (Hand of God, Hellboy), and Oscar winner Joe Pesci (The Irishman, Raging Bull).
