Owing to a genetic mix-up involving stem cell research, the recently founded company Infinity Baby, run by the garrulous Neo (Nick Offerman), is able to offer a service for aspiring parents who never want to leave the baby bubble - infants that do not age. Ben (Kieran Culkin), a serial monogamist who says he wants to find the right woman but is always looking for the next one, and his competent pals Larry (Kevin Corrigan) and Malcolm (Martin Starr), are hired to market the service to those keen to nurture. While Ben swipes through his smart phone looking for his next partner, Malcolm and Larry end up having more time with one of the timeless toddlers than we might have imagined. Does having a baby automatically confer some level of maturity? Will Ben's mom, the sarcastic and demanding Hester (Megan Mullally), approve of Ben's new girlfriend (Trieste Dunn)? Will Malcolm recover from a disastrous accident with kitchen cleaner? The answers to these questions and more await in Byington's heady and hilarious potpourri.
