The story starts with Vasu narrating his story from childhood. He has four close friends: Kanagasabhapathi, Kalyanasundaram, Pattabi, and Venky. The five friends worship Seenu Anna for his dedication to friendship, and one day, he advises to them that marriage will spoil friendship. All the friends take this seriously, except for Vasu, who has a liking for girls, and he is forced to promise not to marry lifelong along with his friends. After failing many attempts of falling in love at school and college, he decides to leave to Chennai so that he would get an opportunity to love a girl. He stays with Nelson, who has affairs with many rich and beautiful girls. Nelson persuades Vasu to trap a rich girl, citing that middle-class and college girls will have bigger competition and high expectations, but rich girls have very less expectations, and many guys do not try to date them, assuming that it is impossible to woo them. He hands the pub membership card to Vasu so that he can get to see many rich girls. During a visit to the pub, arrives Deepika in an Audi car with a male friend, who collapses due to excess drinking. Vasu falls in love with her instantly, helps her lift the friend, accompanies her to the pub, and befriends her. However, when he visits her home the next day, she is unable to recall about him since she was drunk the previous night and rejects his love advances. After all the cop thrashing and goons threatening, Deepika falls in love with him. Meanwhile, Vasu's friends come to know about his love affair and threaten him to break up with her, but when he acts as if he is committing suicide, they act as if they accept his love but plan to irritate Deepika and break their love. Deepika gets annoyed by their behavior. Soon, the four friends manage to create a rift between both of them, and the duo gets separated. Deepika gets depressed and decides to marry a family friend who keeps proposing to her from the beginning. Vasu feels depressed after the breakup, and his friends decide that the only way they can see their friend happy is to patch him up with his lady love, and they plot many master plans to stop the wedding. Soon, it is stopped. Deepika then marries Vasu, and they lead a happy life. Vasu also keeps in touch with his friends forever.
Karthik Krish, who had apprenticed under director Shankar in Enthiran, wrote the comedy script and had hoped to sign either actors Jai or Sivakarthikeyan for the role, before selecting Vaibhav. The film began its shoot in March 2013 with scenes shot in Chennai with the lead cast. Initially Ashrita Shetty had signed up to portray the film's lead actress but delays meant that she was replaced by newcomer Sonam Bajwa. Natarajan Sankaran replaced Santhosh Narayanan as the film's music composer, although the latter agreed to sing a song for the film's soundtrack. In April 2014, the film began another schedule with the director remarking that Vaibhav's character in the film would have shades of the role portrayed by Karthik in Mani Ratnam's Mouna Ragam. After a successful screening in September 2014, director Shankar bought the film and made plans to release it, marking a comeback to film production after a four-year hiatus.

Critical reception
wrote, "Kappal fulfils its only purpose — to be funny...here’s actor Vaibhav’s big breakthrough as a solo hero. This Kappal sails strong for the most part". Sify called Kappal a "watchable fun ride with witty dialogues and good writing". Rediff gave the film 2.5 stars out of 5 and wrote, "There may be flaws, but there is no denying that Karthik G Krish’s Kappal is thoroughly entertaining. But do remember to leave your thinking cap at home". The Times of India gave 3 stars out of 5 and wrote, "Karthik G Krish, is not after heavy philosophy but entertainment. So, he constructs the film as a comedy that is often silly, at times offensive but overall funny". silverscreen.in wrote, "Kappal is like that old joke, which only gets better with age. It also sustains the good spirit that the riotous pattimandram of Solomon Pappaiah offers on festive mornings". The New Indian Express wrote, "Directed by a debutant, it’s meant to be a total comic entertainer. But then it depends on each one’s perception of what they feel are genuine comic moments"...going on to add that the film was "comedy probably targeted at the lowest common denominator in the audience".
Box office
The film is reported to have grossed around in TN and from Rest of India and Overseas. The film collected in its full run.
