The series depicts the poor, dysfunctional family of Frank Gallagher, a neglectful single father of six: Fiona, Phillip, Ian, Debbie, Carl, and Liam. He spends his days drunk, high, or in search of misadventures, while his children learn to take care of themselves. The show's producers sought to distinguish this production from previous American working-class shows by highlighting how Frank's alcohol and drug addiction affect his family.
