'Moodar Koodam' is a delicious black comedy that has used fresh and innovative techniques to bring to life a delightful situational comedy that explores several vital social concepts as well.
Circumstances force four strangers Naveen, Vellaisamy, Sentrayan and Kuberan to land in the same jail for minor offences, but they are released soon. In the short span of time they spend together behind bars, an unlikely friendship and camaraderie is forged between these kindred spirits.
Unsure of how to earn the next meal of the day, the group decides to join hands in robbery, swearing to lead an honest life from the proceeds. They decide to rob Vellaisamy's uncle Bhaktavatsalan, who made millions with an initial investment loaned by Vellaisamy's father many years ago. Bhaktavatsalan refuses to help Vellaisamy when in dire need, hence the plan to rob him to recover money that he has earned by cheating hundreds of innocent people.
As one of the group members tries to pick the lock of the supposedly empty house, the door is opened by the mistress of the house, forcing the quartet to take the family hostage. Chaos ensues as the four handle the situation in the most unbelievable yet hilarious manner.
