Bharath, a technical student, has a habit of kissing people nearby when he is both stressed and happy, disregarding social situations. Bharath (Gokul Suresh), from his first sight of Ganga (Arthana), falls in love with her. Somewhere in Thiruvananthapuram city an infamous gangster Ramakrishnan Bonacaud, aka Rambo (Vijay Babu), has a face to face confrontation with CI Pathmanabhan, aka Padayappa (Baiju); grumpy Rambo becomes annoyed and plans to kill Pathmanabhan soon before leaving Kerala. Meanwhile, Bharath is able to requite love from Ganga and one night he stays with Ganga. After this incident Ganga starts to react hypochondriacally and suspects she is pregnant with Bharath's child and preoccupiedly behaves in the gravity of the same. Rambo is able to sketch Pathmanabhan through two bumbling goons (Kumari and Putheri), but before executing Pathmanabhan publicly, shoots his own urinary bladder using his suppressor gun due to an unexpected kiss from Bharath (who has just got confirmation on Ganga's love). Rambo, who after the accident has urinary incontinence and is attached to a urine drainage bag permanently, is enraged and asks his right-hand man (Abu Salim) to round up everyone involved. All the while the police plan to trap Rambo, once and for all, understanding him to be not just a business man but a Don. They set up a meeting with Rambo through Kumari and Putheri on Rambo's hotel terrace. Rambo calls Bharath's number (which Putheri has obtained) and it keeps ringing. Unexpectedly, Bharath comes to the hotel's terrace to discuss with Ganga their problem of confirming whether she is pregnant or not through a pregnancy test kit and switches off his phone. Everyone on the terrace is frozen and unsure on how to respond. Knowing Ganga isn't pregnant, Bharath looks to kiss someone, sees Rambo, and runs towards him to kiss; they both fall. Immediately a shootout starts between the Police and Rambo's gang. Bharath and Ganga escapes through the staircase. Rambo follow
