Tiffany, played by Jennifer Tilly, is a former lover and accomplice of the infamous serial killer Charles Lee Ray, brilliantly portrayed by Brad Dourif. After bribing and then murdering a police officer to acquire the remains of her beloved Chucky, she believes Charles's essence still resides within the doll. In a daring act, she stitches Chucky back together and performs the voodoo ritual that originally trapped Ray's spirit within the doll more than a decade ago. Initially, her efforts seem fruitless; however, Chucky surprisingly comes back to life, startling Tiffany with his return as he smothers her goth admirer, Damien, played by Alexis Arquette.
Determined to regain his human form, Chucky devises a scheme to recover the amulet that Ray wore the night he died. This precious item is buried with his body in a cemetery located in Hackensack, New Jersey. In an attempt to reignite their past romance, Tiffany presents Chucky with a diamond ring he had previously left for her. Chucky bursts into laughter upon realizing Tiffany interprets it as an engagement ring, informing her it was stolen from yet another wealthy victim during his murderous days. Devastated and infuriated, Tiffany locks Chucky in a playpen as punishment.
The following day, Tiffany approaches a young neighbor, Jesse, with a sinister offer to transport Chucky's body across state lines in exchange for cash. Eager to elope with his girlfriend, Jade, and escape her overbearing uncle, Chief Warren Kincaid, played by John Ritter, Jesse accepts the proposition without hesitation.
Inside Tiffany's mobile home, Chucky attempts to charm her into releasing him, but in a mocking move, Tiffany lowers a doll dressed in a bridal gown into his playpen. Enraged, Chucky escapes captivity and tragically kills Tiffany by electrocuting her in the bathtub after dropping a TV into the water. Subsequently, he performs the same voodoo chant, transferring Tiffany's soul into the bridal doll. With her transformed appearance, Tiffany must now assist Chucky in acquiring the amulet if they hope to both regain their human forms.
As the duo masquerades as dolls, they await Jesse's arrival to collect them. Unbeknownst to Jesse, the dolls plan to commandeer his body once they get hold of the amulet. Their journey takes a dark turn when Jade's uncle hunts them down, leading to a series of deadly traps set by the killers. These bloody exploits include a police officer's tragic fate caused by Chucky and a monstrous revelation during Jesse and Jade's unexpected wedding.
When suspicion looms, Jesse and Jade become convinced of each other's guilt amidst the chaos, only to find their friend David in the mix who informs them of the hunt for their lives. As the shocking truth unfolds, David meets a gruesome end at the hands of Chucky, and a radio announcement reveals the police's plans to dig up Charles Lee Ray's body further endangering their mission.
In a desperate attempt to escape, the couple, along with the dolls, switch vehicles to continue their quest. Tensions rise as Chucky and Tiffany bicker over household duties while Jesse accidentally crashes the vehicle, leading to a catastrophic explosion that leaves Tiffany severely injured but still alive. The horror escalates when they reach the cemetery where Chucky forces Jade to retrieve the amulet at gunpoint.
In a twist of fate, Tiffany betrays Chucky in a display of love for Jesse and Jade, ultimately leading to a dramatic confrontation where she stabs him. However, Chucky retaliates, turning the chaotic battle on Tiffany. With quick thinking, Jesse manages to trap Chucky in his own grave while the police Lieutenant arrives, ensuring an end to the malevolent doll’s reign of terror. As the officer assesses the aftermath, he unwittingly triggers another horror as Tiffany springs back to life, with a chilling surprise emerging from her dress.
> "But dying is such a bitch." Chucky's iconic line echoes as the chaos promises to continue even after his defeat.
