In 1959 Los Angeles, Manny Singer, [Ray Liotta], is a recently widowed jingle writer trying to balance work with caring for his grieving daughter Molly, who has fallen silent after her mother Annie’s death. To fill the void, Manny hires a housekeeper-nanny, and Corrina Washington, [Whoopi Goldberg], interviews for the job; Molly responds to Corrina right away, and she quickly forms a deep bond with her. Corrina establishes a simple, nonverbal way for Molly to say “yes” or “no” with a nose tap, and she gently tells Molly that her mother is in heaven. Manny—an atheist, and the late Annie’s partner in belief—struggles with this religious approach, making their dynamic delicate from the start. Molly also begins to spend time with Corrina’s family and is introduced to their church community.
At an office party, Manny is introduced to Jenny Davis, [Wendy Crewson], a cheerful divorcee with two young sons, but he is not yet ready to date as he works through his grief. Corrina’s sister Jevina, [Jenifer Lewis], nudges Corrina to consider dating Anthony, a man from their community, yet Corrina herself shows no interest in that path. The tension surrounding Molly’s school and her growing bond with Corrina deepens when Molly returns to an all-white school and is mocked for including Corrina in a family portrait. Desperate to belong, Molly asks Corrina to stay home from school, and Corrina secretly agrees, taking Molly along on a second job cleaning other clients’ homes. Corrina’s involvement becomes increasingly indispensable, even helping Manny craft a fresh jingle and rhyme for a Jello campaign.
As Manny and Corrina’s teamwork and affection deepen, they discover shared values, humor, and a love of music that sustains them through prejudice and doubt. After the successful Jello advertising campaign, Manny returns home with flowers for Molly and Corrina, planning a celebratory dinner. Jenny’s unannounced visit disrupts their plans, and Corrina leaves when Manny doesn’t disclose their prior arrangements to her. The tension escalates, and the next day Corrina arrives flustered; they argue, yet their moment ends with an awkward kiss on the cheek witnessed by a nosy neighbor as Manny heads to work.
That night, Manny and Corrina speak about their absent spouses, share a moonlight dance, and kiss openly, witnessed by Molly. Molly, sensing the shift, asks Grandpa Harry, [Don Ameche], to help ensure that Manny and Corrina will marry. As their feelings deepen, they face the harsh reality of prejudice against their interracial pairing, testing their resolve and commitment.
After weeks of Molly skipping school, Corrina tells her she must return to class, and a furious Manny learns of the deception. He fires Corrina, and Molly withdraws again. Then comes the news that Harry has died, casting another ache over Manny’s grief. Following Harry’s funeral, Manny visits Corrina to apologize, and Corrina overhears Manny’s earnest prayer to God for help. She tells him she quits as his employee, and he reassures her that she has been replaced, before embracing and inviting him inside to meet her family.
In the final moments, Molly remains a beacon of resilience, singing This Little Light of Mine to cheer her grandmother Eva, [Erica Yohn] who joins in the song. When Manny and Corrina return, Molly runs to Corrina with a joyful embrace, signaling a hopeful new chapter for their blended family.
