Blue-collar Paulie prepares for fatherhood and his forthcoming wedding to Sue by hanging out with his groomsmen. Brother Jimbo, cousin Mike, and his pals fill the reunion with drinking, boys-will-be-boys antics and a few unexpected personal confessions. But, when the bonding devolves into accusations and regret, Paulie has to decide whether he's ready to tie the knot and take this big step into adulthood.
Unfortunately the movie The Groomsmen is not yet available on HBO Max.
