Faction feud in Tamil Nadu results in the death of Singaraayar's (Nagineedu) brother and he, along with his two sons Dharma (Ravi Prakash) and Kaali (Sugunthan), vow for revenge. Time turns and comes to Chennai. Here lives Sakthi (N. Santhanam), an innocent and somewhat unlucky guy whose parents are no more and is ousted out of his job. His life takes a turn with a correspondence that he has got five acres of land in his hometown in Tamil nadu. He decides to sell that land and sets off to the village. In this process, he also meets Vaanathi (Ashna Zaveri) who is the daughter of Singaraayar. However, much to Sakthi's bad luck, he happens to be the son of the man who killed Singaraayar's brother and he ends up in their home itself. He takes advantage of a tradition of their house that not even one drop of blood should fall inside the house. Vaanathi falls for Sakthi in the mean time. He escapes in all the plans much to the fury of Singaraayar. Soon the story takes a twist when Vaanathi, not knowing that Shakthi is the son of the man who killed her father's brother, falls for Shakthi. Her cousin Raja comes to know about this and refuses to marry Vaanathi, though Shakthi had convinced him earlier in order to prolong Singaraayar's plan. Singaraayar had moved the engagement to the temple so Sakthi cannot prolong the plan to kill him any longer. When Raja tells Singaraayar about Vaanathi's love, he slaps Raja. And in the engagement Dharma carries a basket he thinks Shakthi is hiding in, away from the temple to kill him. It is then revealed that Shakthi is still in Singaraayar's mansion. Then he runs away from the house only to be chased by Singaraayar's men. But Shakthi narrowly escapes from his death and is saved by Vaanathi. When he crosses a bridge which is located at a very high place, he refuses to let Vaanathi come with him and now Vaanathi comes to know the truth and is heartbroken. Soon Singaraayar and his men arrive to kill Shakthi. He somehow escapes. But suddenly Vaanathi tells her father that she was the one who loved Shakthi. Shakthi has a change of heart and decides to go back to Singaraayar to express his feelings to Vaanathi. Singaraayar orders his men to beat Shakthi. First an angry Dharma punches Shakthi, and is followed by 2 3 blows, then he hits a rod and loses consciousness and loses his breath and bleeds badly. Vanathi can't bear this and jumps to the river. Shakthi saves Vaanathi while the family had just watched in shock. Singaraayar and his sons are stunned and realize they must end the feud, and in the end Shakthi marries Vaanathi.
The rights of S. S. Rajamouli's 2010 Telugu film Maryada Ramanna were sold to Prasad V Potluri for 35 lakh rupees. In October 2012, the production team announced that Santhanam would play the lead role in the venture, while R. Kannan would direct the film. Kannan subsequently opted out of the film, noting that he was unhappy on the first-copy production agreement which had been put in place, and was replaced by comedian Srinath, who had previously directed Muthirai (2009).
Delays in starting the film led to reports that Santhanam would be replaced by Siva Karthikeyan in the lead role, but this proved to be untrue. The team confirmed the title would be Vallavanukku Pullum Aayudham in June 2013, confirming that pre-production work was under way, with Anirudh signed on as music composer. Anirudh however dropped out of the project in early July 2013 owing to a busy schedule and was subsequently replaced by Santhosh Narayanan, who had achieved success for his work in Pizza (2012) and Soodhu Kavvum (2013). Santhosh was also replaced by Siddharth Vipin who earlier composed for Idharkuthane Aasaipattai Balakumara, apart from composing he was also selected to act in the film.
The team began shooting in mid September 2013 by filming scenes at EVP World, the amusement and theme park in Poonamallee on the Chennai to Bangalore highway. Mumbai based model Ashna Zaveri was signed on to play the leading female role, thus making her debut as a film actress.
The film's soundtrack was scored by Siddharth Vipin and the lyrics were penned by Na. Muthukumar, Madhan Karky, Lalith Anand and Muthulingam.
The satellite rights of the film were sold to Sun TV. The film was originally planned for a later release, but was advanced and opened in theatres on 10 May 2014 after Rajinikanth's Kochadaiiyaan, which had originally been scheduled for that weekend, was delayed. Studio Green acquired the film's distribution rights only two hours after Kochadaiiyaan's postponement had been announced and released the film in over 250 screens in Tamil Nadu.
The Times of India gave the film 2.5 stars out of 5 and wrote, "Vallavanukku Pullum Aayudham is an example of how most of our filmmakers are clueless when it comes to economy of storytelling...the film only keeps reminding us what a better film its source, SS Rajamouli's Telugu film Maryada Ramanna (2010), is...though director Srinath opts for a frame-to-frame remake, the momentum is missing in the scenes, turning the film into a drag, even for those who haven't seen the Telugu film". Rediff gave it 2 stars out of 5 and wrote, "The plot may have worked earlier, but unfortunately Santhanam’s Vallavanukku Pullum Aayudham is slow and unexciting and does little to keep the audience entertained".
Sify wrote, "What works for the film is its simplicity in storytelling and the light hearted screenplay and steady stream of clever one-liners and witticisms", calling the film a "Time Pass Entertainer". Deccan Chronicle gave it 3.5 out of 5 stars and called it "an entertaining film through and through" and added, "Director Srinath plays on Santhanam’s strengths and delivers a clean entertainer. As a commercial film, Vallavanukku Pullum Aayudham surely hits the spot". Behindwoods gave it 2.5 stars out of 5 and wrote, "Director Srinath has made every possible attempt to remain unpredictable, however falls prey to the restrictions of a commercial masala, which can be neglected as there appears to have been no compromise in the level of entertainment". Indiaglitz wrote, "The key plus points of the film are the art direction and music." The online aggregation portal Silverscreen.in wrote, "That Santhanam is the antithesis of a hero makes the film immensely plausible." and also computed an average aggregated Silverscore of 6/10 for the movie based on published reviews.
