From the liner notes

That Girl ran five seasons on ABC (following Bewitched)from 1966-1971. Marlo Thomas’ character, Ann, was groundbreaking as an independent female forging her own way and forever changed the manner in which women were portrayed on TV, influencing the development of many of the other successful female-lead shows that followed, from The Mary Tyler Moore Show to Kate & Allie and more.

In Season One, Ann Marie is a struggling actress living in New York City. In between trying to find acting and modeling jobs, she shares time with her boyfriend, Donald Hollinger, and attempts to convince her dad, Lou Marie, that she can make it on her own.
