The series follows Louie, a fictionalized version of C.K., a comedian and newly divorced father raising his two daughters in New York City.
In the episode, Louie's pregnant sister visits him, experiencing severe pain, so Louis gets the help from his neighbors.
While the girls stay with him, Louie is taken aback when Jane (Ursula Parker) states that she prefers everything with her mother, unsettling him.
Her screams alert Louie's neighbors, Peter (Frederick Hill) and Pedro (Yul Vazquez), who offer to help her.
Seeing her condition, Pedro states that Louie must help him in taking her to the hospital, while Peter stays to watch the girls.
