Buzzer follows Jackson, a man who left his tough Brooklyn neighborhood by winning a scholarship to Exeter, where he met Don, a play-hard rich boy who became his unlikely best friend. Now a Harvard-educated lawyer, Jackson’s bought a place in the newly gentrifying area he grew up in. But Jackson’s white girlfriend, Suzy, isn’t so sure she belongs in a community “on the verge.” When Don comes to crash with his old buddy and stay clean, his stories of the neighborhood's dangerous past collide with the growing disconnect between Jackson and Suzy and the sexual and racial tensions waiting just beyond the door.
