Nutty Professor II: The Klumps

Professor Sherman Klump successfully devises an innovative de-aging formula that could change the course of his life. This groundbreaking development piques the interest of the scientific community and sets the stage for the events to unfold.

Sherman begins a romantic relationship with DNA researcher Denise Gaines, who is instrumental in isolating genetic material. Their bond deepens as they collaborate in their respective research areas.

During an emotionally charged moment, Sherman plans to propose to Denise, but his alter ego, Buddy Love, interrupts and causes chaos. The situation escalates into a public spectacle, leaving Sherman embarrassed and questioning his control over his identity.

Determined to eliminate Buddy from his life, Sherman decides to use Denise's revolutionary techniques to isolate Buddy's DNA. He ignores warnings from his assistant Jason, putting himself at risk in the process.

A crucial experiment goes horribly wrong when a hair from Jason's Basset Hound, Buster, contaminates the DNA mix. This unexpected twist results in Buddy becoming a living entity, further complicating Sherman's life.

After an awkward apology, Sherman manages to reconcile with Denise, leading to their engagement. The couple finds happiness, but it is short-lived due to impending external pressures.

Dean Richmond announces that Phleer Pharmaceuticals is willing to pay a staggering $150 million for Sherman's youth formula. This revelation puts immense pressure on Sherman to protect his invention.

In a movie theater encounter, Buddy takes advantage of Sherman's situation, ultimately discovering the lucrative contract. He partners with Leanne Guilford to propose a competing bid for the youth formula.

Sherman begins to notice alarming changes in himself, particularly a significant decline in his intelligence resulting from the problematic DNA extraction. Concerned about his condition, he takes urgent measures to safeguard the youth formula.

In an unexpected turn, Sherman's father, Cletus, inadvertently consumes some of the youth formula during a nightclub outing. This leads to an embarrassing situation as he attempts to seduce Sherman's mother, Anna, who is horrified.

Seizing the opportunity provided by Cletus' mishap, Buddy figures out how to steal the youth formula from the Klump household. He concocts a nefarious plan that will have dire consequences during a public demonstration.

During a disastrous demonstration of the youth formula, Petey, a hamster intended for display, mutates into a gigantic and chaotic creature. This unexpected incident disrupts the event, leading to mayhem.

Following the disastrous demonstration, an enraged Dean Richmond fires Sherman, leading to a confrontation with Jason. Faced with the reality of his declining mental health, Sherman decides to end his relationship with Denise.

In a moment of clarity, Cletus comforts Sherman and reveals that to restore his intelligence, he must reintegrate Buddy Love into his DNA. This pivotal moment sparks hope and a plan for Sherman.

Sherman successfully creates a new formula but must race against time to implement it. After a series of chaotic events, he drinks from a fountain imbued with glowing genetic material, which miraculously restores his intelligence.

The story culminates in the joyful wedding of Sherman and Denise, marking a happy conclusion to their trials. Meanwhile, Cletus and Anna reignite their romance, celebrating love in various forms.
