Kalavani (2010)

Vimalraj (the grubby Meenakshi Sundaram from Pasanga) is the ill-behaved son of the gullible Saranya and her husband Ilavarasu. Vimalraj's financial needs are met by his susceptible mother, whom he either hoodwinks or intimidates to fulfill his frequent needs to gamble or hang out with his friends. He pushes the boat out and spends his time whiling away, aided by his friends. In the course of the time, he also spots a girl and falls in love with her - much to the despair of her brother who nurses a rivalry against him. What happens next forms the climax.
