This story is from the great Hindu Epic Mahabharata.
The Pndavas once performed "Rajasuya Yagna" whith the desire to obtain the lordship of the world. At this yagna they gave the place of pride to Lord Krishna, the Divine Cowherd. This angered Shishupal and the Kauravas. Lord Krishna had promised Shishupal's mother that he would leave Shishupal alone till he had committed his hundredth sin.
In this yagna Shishupal committed the fatal hundredth sin, and Krishna's famous "Sudarshan Chakra" served his head from his body.
Angered by this, the Kauravas decided to teach the Pandavas a good lesson. Knowing Yudhisthir's love for gambling Shakuni and Dur-Yudhisthir's love for gambling Shakuni and Duryadhon persuaded him to play a game of dice. In this game, Yudhisthir lost everything; the Pandavas and Draupadi became the slaves of the Kauravas. The Kauravas banished the Pandavas to solitude for a period of thirteen years.
Balaram, the brother of Krishna, had decided to give his daughter, Surekha, in marriage to Arjun's son, Abhimanyu. When he learnt from Shakuni that the Pandavas had gone into banishment, Balaram decided to give Surekha in marriage to Laxman, the silly son of Duryadhona. When Abhimanyu came to know of this, he set out with his mother, Subhadra, to abduct the beautiful Surekha. In their wanderings, they came to the abode of Ghatotkach, son of Bhima. After the initial misunderstanding, Ghatotkach promised Abhimanyu that he would remain by his side through thick and thin. Thanks to the prowess of Ghatotkach and the cunning of Krishna, the Kauravas were thoroughly humbled, and Abhimanyu succeeded in abducting Surekha.
