Lakhan Singh aka Lucky (Sonu Sood) is the 'king' of the Australian underworld accompanied by his associates (played by Javed Jaffrey, Neha Dhupia, Manoj Pahwa, Yashpal Sharma, Kamal Chopra and Sudhanshu Pande.) Far away, in a small village in Punjab, where Lucky was born, there exists someone more notorious than him - Happy Singh (Akshay Kumar). The village is fed up of his magnanimity, which has resulted in a number of hilariously disastrous situations. Out of desperation, they decide to send him on a long trip (that will keep him out of the village for a while!) to bring Lucky back to Punjab, as his despicable deeds were maligning their image in Australia.
