Grudge Match

Old boxing rivals come out of retirement for one final match. Thirty years later after they've bowed out of the ring, boxing promoter Dante Slate Jr., seeing big bucks in his future, makes them an offer they can’t refuse: re-enter the ring and settle the score once and for all. But they may not have to wait that long: On their first encounter in decades, their long-festering feud erupts into an unintentionally hilarious melee that instantly goes viral. The sudden social media frenzy transforms their local grudge match into a must-see HBO event.

Now, if they can just survive the training, they may actually live to fight again.
