portrays Evelyn. In the present day, Evelyn Wang is stressed out as she tries to sort piles of receipts, as the laundromat is being audited by the
IRS. Her husband Waymond tries to serve Evelyn divorce papers in an attempt to get her attention so they can talk about their marriage. She is also concerned about preparing for a
Chinese New Year party at the laundromat that evening, which her demanding father (Gong Gong) will be attending. When their adult daughter Joy arrives to help them, along with her non-Chinese girlfriend Becky, Evelyn says that she accepts their gay, mixed-race relationship, but implies that her own father would not approve, and avoids Joy's pleas to discuss whether or not Becky is welcome at the party. Unable to have a meaningful conversation with her mother, Joy leaves the laundromat in tears with Becky, and Evelyn is left subdued. In the elevator at the regional IRS office, Evelyn has her first encounter with Alpha-Waymond, a version of Waymond from the "Alphaverse", and sees a flashback of her own life. She is distracted and unable to focus during a meeting with IRS inspector
Deirdre Beaubeirdre, who questions their business expenses, and scolds her for not taking the meeting seriously and for not bringing their daughter to help translate as promised. Meanwhile, Evelyn is having discussions in parallel in a janitor's closet with Alpha-Waymond, who tells her that every disappointment and failure she has experienced in life has made her uniquely qualified to save every world in the infinite
multiverse from catastrophe. Deirdre gives the family an extension until 6 pm that evening, but Evelyn – confused by Waymond's sudden mention of divorce and berated by her father for never completing anything – punches Deirdre, landing them in trouble with security. Alpha-Waymond reappears to help Evelyn out of this difficult situation. She learns, as they dodge security officers and more monstrous versions of Deirdre together, that many
parallel universes exist because every life choice creates a new alternative universe. In the Alphaverse, the brilliant late Alpha-Evelyn developed "verse-jumping" technology, which enables people to access the physical skills, knowledge, and memories of their parallel selves by performing bizarre actions that are statistically unlikely. As chaos ensues around them, Evelyn herself experiences verse-jumping, briefly discovering other versions of herself including the glamorous
kung fu film star that she could have been if she had refused to marry Waymond all those years ago. All universes are now under threat of complete annihilation due to the all-powerful
Jobu Tupaki, whose mind was splintered due to excessive pressure from Alpha-Evelyn; she can verse-jump and manipulate matter at will. When Evelyn has her first direct encounter with Jobu Tupaki, who is dressed like Elvis and coldly and disrespectfully destroys two police officers, it finally hits home with her that Jobu is simply another version of Joy, who is extremely unhappy. Evelyn and Jobu, dressed in a tennis outfit, face off in a tense one-on-one conversation. Evelyn blames Jobu for all of Joy's "failures", while Jobu starts to entice Evelyn with the empty
nihilism of the
Everything Bagel she has built, which has eased her pain with the realization that "nothing matters". As the force of the bagel starts to destabilize the multiverse, Alpha-Gong Gong appears in an electronic wheelchair to temporarily crush Jobu. Alpha-Gong Gong instructs Evelyn to kill Joy to stop Jobu from using her to enter Evelyn's universe. Evelyn refuses and decides to face Jobu by gaining equivalent powers through repeated verse-jumping. Alpha-Gong Gong, convinced that Evelyn's mind has been compromised like Jobu's, sends soldiers after Evelyn. While they fight, Jobu locates and kills Alpha-Waymond in the Alphaverse. As Jobu confronts Evelyn in her universe, Evelyn's mind splinters, and she collapses. Evelyn uncontrollably verse-jumps alongside Jobu across bizarre and diverse universes. Jobu reveals she does not want to fight at all, but that instead, she has been searching for an Evelyn who can see, as she does, that nothing matters. She brings Evelyn to the Everything Bagel, explaining that she wants to use it to allow herself and Evelyn to truly die. Upon looking into the Bagel, Evelyn is initially persuaded, and behaves cruelly and
nihilistically in her other universes, hurting those around her. Just as Evelyn enters the Bagel with Jobu, she pauses to listen to Waymond's pleas for everybody to stop fighting and to instead be kind, even when life does not make sense. Evelyn has an
existentialist epiphany and decides to follow Waymond's
absurdist and
humanist advice, using her multiverse powers to fight with
empathy and bring happiness to those around her; in doing so, she repairs her damage in the other universes and neutralizes Alpha-Gong Gong's fighters. In the universe where humans evolved to have hot dogs for fingers, Evelyn reconciles with her partner Deirdre. In her home universe, Evelyn reconciles with Waymond, accepts Joy and Becky's relationship – and tells Gong Gong of it – while Waymond convinces Deirdre to let them redo their taxes. Jobu decides to enter the Bagel alone while, simultaneously in Evelyn's universe, Joy begs Evelyn to let her go. Evelyn tells Joy that even when nothing makes sense and even though she could be anywhere else in the multiverse, she will always want to be with Joy. Evelyn and the others save Jobu from the Bagel, and Evelyn and Joy embrace. Sometime later, with the family's relationships improved, they return to the IRS building to refile their taxes. As Deirdre talks, Evelyn's attention is momentarily drawn to her alternative selves, before she grounds herself back in her home universe. ==Other versions==
