Eyarkai

Marudhu, a sailor, arrives at Rameshwaram port from Rome. Despite being a Tamilian, he has not visited Tamil Nadu for fourteen years. He plays cards against Dorai and his posse at the bar, which is a popular hang-out spot at the port. Nandu, a man Marudhu met at the bar, tells him which stop on the train to get off to go to the church. Marudhu tells the church father, Stephen, about a nearby ship that capsized and how the ship captain tried to escape. An interested Nancy overhears the conversation. He meets Nancy again at a roadside restaurant run by her sister-in-law, Mercy. One day, Nandu comes to the bar with a bandage over his nose and after Marudhu learns that Dorai and his men did it, they engage in a fight. While fighting Dorai, Marudhu asks him who is he looking for and if it is his lover. Nancy overhears this dialogue, which keeps playing in her head while walking on the train tracks causing her dress to get stuck on the track. Marudhu sees Nancy about to get hit by an oncoming train and saves her. She tells Marudhu to come to the lighthouse at 6 p.m. Later that day, Marudhu is told by the ship crew to get something that was stuck out of his ship's propeller. However, the propeller turns on and Marudhu gets injured, making him unable to come to the lighthouse. To Marudhu's dismay, Nancy tells him that he was not waiting for him, but for a ship captain that she met three years ago. She had first met the ship captain while selling mangoes and had fallen in love with him. However, the ship captain had told her that she can't make a proper judgement about love because she was too young. The ship captain had told her not to wait for him. He gives her a ring and after Nancy repeatedly tells him to return in a year, the ship captain changes his mind and says that he will come back in a year. Marudhu helps Nancy in her search for the ship captain. Nancy does not know the captain's name since she only addressed him as "Sir" and "Officer", making the search more difficult. She starts to distance herself from Marudhu after he reveals his love for her. One day, Nancy eventually comes across Joe, the ship captain's crewmate, after recognising him in the bar. He tells Nancy that the ship captain's name is Mukundan and that he died in a shipwreck. Mercy wakes up the next day and realizes that Nancy is missing. She tells Marudhu to go find Nancy. He gets on a ship docked at the port and finds an emotionally unstable Nancy sitting there. Marudhu tried to get her off the ship when a man named Adam tells him that he cannot take her unless he fights him. After the fight, Nancy jumps off the ship and Marudhu jumps off to in order to save her. Nancy and Marudhu go on a canoe at night in search of Mukundan when Marudhu accidentally loses Nancy's ring. The next day, he returns to ring Nancy and tells the church father that he and his ship crew are planning to leave on the night of Christmas. He writes his name on one piece of paper and "Captain" on the other and asks the church father to choose one of the papers. On Christmas Eve, Mukundan arrives unbeknown to Nancy, and Marudhu sees him, although Marudhu does know that the man he helped is Mukundan. Marudhu asks if Nancy is willing to accept his love. He starts the open the piece of paper to see whose name is written before Nancy stops him and agrees to marry him the next day, on Christmas. During the wedding, Nancy sees Marudhu and a bunch of other men dancing with Santa Claus masks. One of the men kneels and presents a ring to Nancy. To Nancy's surprise, the man removes his mask, revealing that he is Mukundan and not Marudhu. A depressed Marudhu leaves the port aboard his ship as the wedding celebrations continue.
