It’s Always Sunny in Philadelphia

The gang gets involved in trash and dirty tactics when Dee and Mac find an abandoned baby boy in a Dumpster and try to care for and make money off him, Frank and Charlie get into Dumpster diving (with Charlie still trying to find out whether or not Frank is his real father), and Dennis tricks an environmentalist into chaining himself to a tree to save it from being cut.

When the Philadelphia Eagles hold open try-outs à la the movie Invincible, Mac, Dennis, and Dee use the event for their own personal competition. Meanwhile, Frank and Charlie go to a tailgate party, where Frank trips on LSD and make things worse between them and the McPoyle family.

Frank’s ex-wife Barbara dies (for real, this time), leaving behind a big inheritance that Frank and Dee will do anything to get. Meanwhile, Mac, Dennis, and Charlie use Barbara’s house as a men’s club to make new male friends ("nothing sexual").

The Gang is held hostage in Paddy’s Pub by the McPoyles. Meanwhile, Frank crawls through the vents (a la Die Hard) to find his will, which Charlie hid.

The gang gets involved in the world of fashion design after Dee gets jealous of her former high-school best friend, who is now a successful boutique owner. Meanwhile, Frank starts up his old sweatshop business and coaches Mac on how to run one.

The gang find themselves at odds with a more successful Korean pub owner who bears a striking resemblance to former North Korean dictator Kim Jong-Il. Meanwhile, Charlie becomes involved with the owner’s daughter.

When a restaurant chain offers to buy Paddy’s Pub the guys try to make the deal go through by attempting to show the rep a good time. When she finds out she won’t get anything out of the deal, Dee quits her job at Paddy’s (again) and pressures The Waitress to get her a job at a TGIFriday’s-style restaurant.

The gang tries to become local celebrities by creating their own public access news show and making it big on the hip club scene.

Dee begins dating an amateur rapper and Dennis tells her that he is mentally retarded. Meanwhile, Frank, Charlie, and Mac start their own band but can’t agree on what type of music they should play, especially when Charlie pens a disturbing song about being molested by a strange creature called The Night Man.

After reading about a serial killer terrorizing young women, half of The Gang suspects that Mac may be the serial killer when they notice how distant he’s become and the other half try to catch the serial killer themselves. Mac secretly renews his relationship with Carmen, the transsexual woman.

Dennis’ life goes downhill when the community mistakes him for a convicted sex offender that has been released from prison due to overcrowding. Meanwhile, Mac and Charlie reunite with Mac’s convict father.

Part one of two. The gang find themselves married to the mob when they sell a bag of cocaine that a group of mobsters hid in a pair of speakers. Initially to pay off the debt, The Gang buys more drugs and attempts to sell them at a country club.

Conclusion. The gang must find a way to avoid getting "whacked off" when their plans to pay off mob members for missing cocaine go awry. Frank ends up whoring out Dennis to older women. Mac tries to become a member of the mob. Charlie and Dee stick to the plan to sell drugs but use them all themselves.

Mac and Dee become vigilantes to solve the homeless problem. Meanwhile, after buying a junkyard police car to scare the homeless away from the bar, Frank and Dennis dress up in police costumes and begin to abuse the public while Charlie dresses as Serpico and tries to expose them.

Charlie inadvertently puts Paddy’s Pub up as the grand prize in a radio dance marathon, so the gang must win the competition - against the enemies they’ve made so far in the series - to keep the bar.
