Andrew Scott and Hugh O'Conor star in this Irish comedy written and directed by John Butler. Metrosexual groom-to-be Fionnan (O'Conor) would rather go to his fiancée Ruth (Amy Huberman)'s hen party than his own stag do. Ruth, however, manages to persuade his best friend Davin (Scott) to arrange the stag and he opts for a walking holiday. Despite their best efforts to avoid him, they are joined by Ruth's maniac brother known as The Machine (Peter McDonald), who turns the low-key weekend into a series of misadventures. Will Fionnan make it back to his future wife unscathed?
