Thagararu revolves around the lives of four friends, Saravanan (Arulnithi), Pazhani (Sulile Kumar) Senthil (Pawan) and Aarumugam (Murugadoss), who live in the city of Madurai. They are orphans, who have been together since childhood. Learning to fend for themselves, they fall into bad ways and grow up to be rough, violent, bad-tempered alcoholics, who have perfected the art of thievery. They share a special bond, protecting and supporting each other, and have a special affection for Saravanan, the youngest of the lot.

Saravanan meets and falls in love with Meenakshi (Poorna), the daughter of a dangerous moneylender, Kanthuvatti Rajendran (Jayaprakash). Though Meenakshi reciprocates his love, she is extremely possessive and resents the love he shares with his friends.  His friends too, feel threatened by her and fear that she will separate them. With each robbery, they become more and more arrogant, making numerous enemies and even antagonising a newly appointed inspector of police, who vows to catch them.  Towards the end of the first half, Pazhani gets killed. With a long list of people wanting them dead, they have absolutely no clue who is the killer. How they avenge the death of their friend forms the rest of the story.
