It's Always Sunny in Philadelphia features Mac, Dennis, Charlie, Sweet Dee and Frank, five ne'er-do-wells who own and operate Paddy's Pub in Philadelphia.

Their constant scheming usually lands them in a world of hurt, yet they never seem to learn from their mistakes.

As they say, some things never change.

So prepare for more depraved schemes, half-baked arguments, and absurdly underhanded plots to subvert one another.

The fan-favorite, ever-inventive series marks the 20th anniversary of its series premiere this year. The new season will include The Gang's take on meeting ABC's Abbott Elementary in the conclusion to the highly-anticipated crossover.

In the latest season, "The Gang Embraces The Corporate Era:" The story of how greed and the New American Dream have consumed Paddy's Pub.

Seventeen seasons on, the gang return to shamelessly shed their "niche" label for grander aspirations.

They'll exploit cross-network promotion to increase market share; they'll scapegoat one of their own to avoid a PR backlash; they'll risk everything for a handshake with the Saudis; they'll bend the laws with side hustles to pad their pockets; and they'll change everything about themselves to appeal to a broader audience.

And sure, like any corporate goon, the Gang craves money and parasitic social privileges. That's been plain since 2005.

But they're also human beings. They crave love... respect... conditional freedom... constant adulation... histrionic amounts of attention... non-stop gratification... and unfiltered, slaphappy eroticism.

In Season 17, they'll chase down them all.

And the money. Obviously, the money. They don't want to spend the rest of their lives working like dogs.

In the Season 17 premiere, "The Gang F***s Up Abbott Elementary": Months after the Gang visited, Abbott's Principal Ava walks viewers through some of the unseen footage of the Gang's volunteerism and reveals their true intentions.

It's Always Sunny in Philadelphia was created by Rob McElhenney.

The show is produced by FX productions.
