'That's My Baby' is a joyous look at maternal instincts gone awry. When two women in a park claim the same child, tempers flare and a fight ensues. Although neither seems to have much of an understanding of parenting, both throw their conflict to the wind when the child's safety is threatened. Who is the real mother? Could the child have two mothers? What is the best for the child? Assumptions about property and parenting are a soft undercurrent in this hilarious physical comedy.
