Flailing thirty-four-year-old Bridget (Kelly O'Sullivan) finally catches a break when she meets a nice guy and lands a much-needed job nannying six-year-old Frances (played by a scene-stealing Ramona Edith-Williams). But an unwanted pregnancy introduces an unexpected complication. To make matters worse, she clashes with the obstinate Frances and struggles to navigate a growing tension between Frances's moms. Amidst her tempestuous personal relationships, a reluctant friendship with Frances emerges, and Bridget contends with the inevitable joys and shit-shows of becoming a part of someone else's family.
