Daniel Lieberman, portrayed by Jake Hoffman, along with his friends Paul Halston-Myers, played by Jake Lacy, and Matt Walker, depicted by Sinqua Walls, navigate their lives in New York City, where a significant moment awaits for Daniel as he plans to propose to Erin, performed by Heidi Gardner. However, upon arriving at Erin's apartment, he finds an unexpected sight—a naked man in his fridge, while Erin emerges from the bedroom, also mostly undraped, leaving Daniel in a state of shock.
Meanwhile, in Poughkeepsie, New York, the story shifts focus to three mothers: Carol Walker, brilliantly played by Angela Bassett, Gillian Lieberman, brought to life by Patricia Arquette, and Helen Halston, portrayed by Felicity Huffman, who gather annually on Mother's Day. They bond over their mutual disdain for their sons' neglect in recognizing the holiday, expressing their frustrations and feelings of isolation. Despite their long-standing friendships, their sons seem to live in worlds apart, which leads the mothers to coin the term "Otherhood" to describe their emotional condition.
As they engage in conversation, it's revealed that Gillian teaches piano to stay connected with children. Carol struggles with loneliness as she clings to her large house, while Helen becomes overly fixated on her appearance. Their desires to reconnect with their sons unfold into a plan when Helen suggests a road trip to surprise them.
The mothers embark on their adventure, only for Carol to find a female garment in Matt's living space, prompting her to tidy up. Helen, meanwhile, feels insecure about their mother's visit and opts for a hotel while Gillian also seeks accommodation. As the night progresses, they each try to reconnect with their sons. Helen confronts Paul about his life choices, and Gillian pushes Daniel to date again, but struggles with feelings of resentment toward Erin.
The unfolding chaos escalates as all three mothers find themselves dealing with the realities of their children’s lives, from discovering unflattering truths about relationships to confronting their past decisions, revealing how deeply intertwined their lives and choices are. They share laughter, tears, and revelations about abandonment, personal insecurities, and the complexities of motherhood.
The narrative crescendos when they decide to explode their bubbles through wild nights out and painful heart-to-heart conversations, leading to some surprising outcomes and resolutions. They learn that closure comes from genuine communication with their sons and reflective self-growth. When it all culminates, a year later, we see the characters at Gillian's house for Daniel and Erin’s wedding, illustrating how far they've all come, having navigated their tangled relationships, accepted their pasts, and embraced new beginnings together.
