Park Street Under is a sitcom set in a fictional bar in the Park Street subway station in Boston, Massachusetts. It was produced starting in 1979 by Boston television station WCVB-TV. This was a rare example in the United States of a half-hour sitcom produced by a local station during the 1970s. Park Street Under was an inspiration for the NBC sitcom Cheers, which was also set in a fictional Boston bar. The cast included James Spruill, father of filmmaker Robert Patton-Spruill. The scripts were by Jonathan Stathakis and Stu Taylor. Park Street Under is also the original name for the Red Line subway platform at Park Street, which is literally under the streetcar lines that became the Green Line.

Hazel runs a beauty salon out of her house, but makes extra money by providing ruthless women the oppurtunity to perform hit jobs. L.T. is a parasite, and contacts Hazel looking for work after he runs out of money. She is reluctant to use him for a hit, since she prefers using women, but decides to try him on a trial basis. Meanwhile, the cop she pays off wants an arrest to make it look like he's doing his job, but Hazel doesn't want to sacrifice any of her "associates". The sleazy side of life is explored in this delightfully dark and deadpan film.
