Based on the BBC UK original series "Miranda," created by Miranda Hart, Call Me Kat stars Emmy Award nominee Mayim Bialik as Kat, a woman who struggles every day against society and her mother to prove that she can live a happy and fulfilling life, despite still being single at 39.

Although Kat celebrates her independence, her single-forever plans may begin to veer off-course, when her former crush and good friend, Max, returns to town.
