FX has set Monday, August 17 for the Season 18 premiere of It’s Always Sunny in Philadelphia. It returns with an expanded 10-episode season, up from eight episodes in the previous three seasons.

In season 18, Charlie, Mac, Dennis (Howerton), Dee (Olson), and Frank (DeVito) are wrapped up in salvaging inheritances from a dead woman, surviving tent encampments and the great inside-outside divide between the haves and have-nots, withstanding job loss at the hands of workplace automation, embracing a newfound appreciation for neurodivergence, questioning the fabric of society against conspiracy theories, and of course — the biggest elephant in the room — outlasting the public’s pendulum swing against drinking. Not to mention battling nerds, LARPers, and a particularly petulant McPoyle clan at the Renaissance Faire or sportswashing their way back into the good graces of their community by sponsoring a Little League team. All the while trying to maintain order in their personal lives and at Paddy’s, which have become increasingly lawless and erratic.
