The film begins with It's Prashanth, a movie reviewer, receiving a special show ticket for "Hitchcock Iruthyaraj," a film directed by Hitchcock Iruthyaraj himself. At the Cinema Paradise theater, Prashanth finds himself alone and soon becomes trapped. He witnesses Hitchcock Iruthyaraj brutally killing movie reviewers who gave poor reviews. The film intertwines with the killings, and by the end, Hitchcock Iruthyaraj and his assistant are shown to be killed, with Prashanth being trapped and killed by Hitchcock's spirit.
Krishnamoorthy "Kissa 47," a sharp-tongued YouTube film reviewer, known for his honest critiques, receives an invitation to a private screening of Hitchcock Iruthyaraj's latest film, "DD Next Level." Kissa visits the dilapidated theater, suspects something is off, and escapes. However, Kissa's family and girlfriend, Aasai Harshini, unaware of the danger, attend the screening. Kissa rushes to rescue them and finds himself trapped with two other reviewers, "Veen Pechu" Babu and "Veen Pechu" Mani, thrown into the film by Hitchcock Iruthyaraj's spirit.
In the film, Kissa finds himself trapped in a haunted cruise ship, and a masked assailant kills Mani. Iruthyaraj appears outside the screen, challenging Kissa and Babu to survive until the end credits roll to escape the film and return to reality. Kissa's family members, including his father Auto Baskar (now Captain McDonald), mother Devaki (now Shilpa, a Telugu-speaking actress), and younger sister Devi (now Maya, the film's female lead actress), no longer recognize him. Kissa meets the film's lead actor, Ragavan, and his assistant, Gopal, but they don't understand him. Iruthyaraj hints that Kissa's mother, Shilpa, is destined to be killed according to the film's script. To save his mother, Kissa directs the masked killer to himself and gets beaten unconscious.
The cruise ship passengers move to a nearby island, Cuckoo's Nest, owned by Robert. Kissa and Babu hear the voice of Aasai Harshini, now known as Jessica Sebastian, and are shocked to see her portrait in the resort. Kissa learns that Jessica Sebastian went missing years ago, and the island is said to be haunted by her spirit. A tribesman hints to Kissa and Babu about a diary hidden on the third floor of the resort, which might reveal ways to escape the dangers. Before they can investigate, the other passengers, including Maya, Shilpa, Gopal, and Arumugam, enter the haunted room, fearing spirits. Meanwhile, Ragavan suspects the resort owners are cannibals and holds them at gunpoint, but the masked killer, revealed to be Robert, apprehends Ragavan. Robert chases Maya, Shilpa, Gopal, and Arumugam, but Kissa helps them escape. Kissa ventures to retrieve the diary from a deep pit with the help of a rope. However, as soon as he opens the diary, the spirit of Jessica Sebastian is unleashed. The witchcraft woman orders Robert to fetch Jessica's diary to destroy her soul permanently.
Despite the diary changing hands multiple times, Kissa eventually retrieves it. With the diary, Kissa plans to travel to the past to prevent Jessica's death and the curse that haunts the island. As Captain reads the diary, the flashback reveals Jessica's story. She had purchased the island and resort, only to discover Robert's activities of killing humans as sacrifices to their forefathers. Before Robert could kill her, Kissa and Babu travel to the past and safeguard her, killing Robert and his men in the process. With the curse lifted, Kissa rejoices, thinking they can now safely return to the real world. However, Iruthyaraj reveals a twist: by saving Jessica, Kissa has inadvertently brought back to life the man-eating cannibals that Jessica's spirit had previously killed. Kissa asks Iruthyaraj how to escape the trap, and Iruthyaraj replies that Kissa must fight them off to safeguard his family.
Kissa, along with Babu, Ragavan, Arumugam, Jessica, and Gopal, embarks on a mission to rescue his family from the cannibals. As they fight the four cannibals, the film's rolling title symbolizes their limited time. Kissa and Ragavan kill one cannibal, and the Captain's idea sets a room full of traps, but Arumugam and Gopal get caught and die. Kissa and Babu use a huge metal ball to kill another cannibal, and a bomb blast kills the third one. However, Babu sacrifices himself, considering his wastrel nature in the real world. With everyone's help, Kissa finally kills the last cannibal. But just as they think they've won, the four cannibals return to life, hinting at a sequel, "DD Never Ends". A black hole appears, sucking Kissa's family and girlfriend into it. Iruthyaraj laughs, expecting Kissa to continue the cycle. However, Kissa outsmarts him by killing Ragavan, ensuring there's no hero to continue the sequel.
Kissa tells Iruthyaraj that reviews don't define a film's quality, and finally Iruthyaraj sets Kissa free, and he returns to the real world, where his family is safe. The film ends with fake and paid reviewers entering the theater.
