Conqueror of Destiny) is a 1978 Indian action crime drama film produced and directed by Prakash Mehra, and written by Kader Khan, Vijay Kaul and Laxmikant Sharma.

The film tells of the story of Sikandar (played by Amitabh Bachchan), an orphan raised in the slums of Bombay.

Muqaddar Ka Sikandar was the highest-grossing Bollywood film of 1978,[4] and the biggest Diwali blockbuster of all time.

The story revolves around a nameless, young orphan boy who finds employment in the house of a wealthy man, Ramnath, played by Shriram Lagoo.

Later on, the boy is adopted by a Muslim woman named Fatima, portrayed by Nirupa Roy, who also works for Ramnath.

However, things take a turn for the worse when Sikandar is accused of trying to rob Ramnath's house while attempting to deliver a birthday gift to Kaamna.

In the midst of his grief and despair, Sikandar seeks guidance from a fakir named Darvesh Baba, played by Kader Khan.

The wise Darvesh Baba advises Sikandar to find happiness in sadness and embrace the challenges of life.

The film cuts to grown up Sikandar (Amitabh Bachchan), revealing he has amassed a fortune by turning in smugglers and thieves to the police and receiving the reward payouts.

One night in a bar, Sikandar is introduced to Vishal Anand (Vinod Khanna), a down-on-his-luck lawyer.

At length Ramnath and Kaamna, who have been struggling financially, discover that Sikandar has been anonymously paying their bills.

Sikandar, upon learning this, struggles with his emotions but decides he must sacrifice his love for the sake of his friendship with Vishal.

Meanwhile, the marriage of Mehroo is at risk of being cancelled; her fiancé's family have learned about Sikandar's frequent visits to Zohra, and they object to the union on these grounds.

When she is unable to stop his entry, she kills herself by consuming poison hidden in her diamond ring, and dies in his arms.

His dying words inadvertently reveal his love for Kaamna, and Vishal sings him a reprise from the movie's theme song: "Life is going to betray you someday... Death is your true love as it will take you along..." Sikandar's entire life flashes before him and he dies in Vishal's arms just as the song is completed.
