Madhubala – Ek Ishq Ek Junoon

Madhubala "Madhu" Choudhary was born on a film set and works in a parlour while her family members are junior artists in the Mumbai film industry. She fights a case of hit and run on behalf of Mukund against Bollywood superstar Rishabh Kundra "RK" who gets sentenced to jail. Mukund proposes to Madhu and they get engaged. RK insinuates that Madhu is his girlfriend and humiliates Padmini and Shamsher's relationship, saying they have been having a secret affair for the last 20 years.

Mukund breaks off his engagement thinking Madhu has had an affair with RK. She slaps RK, who puts forward an offer for Shamsher's treatment, as he was badly beaten up on RK's set. RK proposes to Madhu and she accepts. Rude and egotistical, he becomes hell-bent on ruining her life. Eventually, Madhu begins falling for him. Sikandar's wife Deepali wants her to leave RK but her wishes are in vain. Shamsher shoots RK; Madhu donates her blood to save him.

No longer rude to Madhu, RK begins loving her. She restores his relation with Radha and the two confess their love; RK helps Padmini and Shamsher in getting married. Balraj abducts all but is shot to death by Padmini. RK needs a break and says he wants to marry Madhu properly so they can take their marriage forward; but suddenly, he tells he'd never loved her as it was his plan all along to entangle her in his love and then destroy her life when he leaves her.

Devastated, Madhu moves on. Everyone convinces RK to bring her back but he does not budge on his decision. Madhu gets a job as a hairstylist at RK's film set. He is again rude to her and adamant to make her leave. Later he decides to win her back and abducts her and forces her to live with her at his home. Madhu does not relent. Sultan enters. Madhu leaves saying she will not come back unless RK confesses his love. He finally proposes to her, and they unite.

The preparation for grand wedding begins. Sultan falls in love with Madhu, and is now vengeful on RK. Being his half-brother, he uses this to humiliate him. Sultan refers to RK as a bastard as Mohan firstly married Meera. Sultan fakes his death and RK is jailed, until Madhu learns the truth. Sultan asks her to divorce RK and come to him to save him. Helpless, Madhu agrees. Enraged, RK uncovers Sultan's deeds and eventually kills Sultan with the police to save Madhu.

Due to some reasons, RK is banned from Bollywood and plans to produce his own film. To help him, veteran director Mehul Chopra selects Madhu as the heroine but RK refuses and is actually fascinated by the idea of her being the heroine. RK finds a heroine but is dissatisfied and vows not to pressurize Madhu to sign the film. Thinking his career is over, RK is about to commit suicide when his assistant Bittu informs him Madhu has stepped in as the heroine.

Super excited, RK appears as the lead of his film in front of media with Madhu who marks her entry into Bollywood. He confesses that he loves and thanks Madhu for becoming his heroine. After sometime during shooting, RK is injured and suffers paralysis. Madhu decides to finish the film. RK develops insecurity to her due to her rising fame and being ignored by everyone because he is handicapped. Madhu gets pregnant but RK does not want a baby, breaking her heart.

The film "Ishq Ek Junoon" becomes a superhit, with RK out of his problems. Madhu miscarries and blames him who tries his best to avert her mind from getting into film industry. Later, Madhu turns into a real-life heroine like she was destined to be. RK's look-alike KRK is introduced, hired by Kulbhushan for revenge for RK. KRK agrees to take RK's place being in need of money but leaves his life when he realizes it will be separating him from Madhu.

KRK returns to his hometown with prize money from RK for speaking up the truth and showing decency. Kulbhushan is arrested. Pregnant once again, Madhu gives birth to a girl whom RK also names Madhubala. He prophesies that she will become a superstar like her parents. Later Harshvardhan Kapoor enters the frame who is a film producer and wanted his son Abhay Kapoor to enter the film Industry. He was also the producer of Rk’s 1st film so Harshvardhan wanted RK's help to make his son Abhay’s entry into the bollywood film industry. However, he and his manager Nikhil spoke in a rude way so RK wanted to teach them a lesson by not acting in their film. Later , Harshvardhan threatens RK to "burn him alive" because of the loss of his money and ruined career of his son Abhay Kapoor. Pam and Nikhil take this as an opportunity to get rid of Harshvardhan Kapoor and to get Kapoor’s property and also RK's property and RK’s mansion too. Then RK, Madhu, Khundra’s family, Bhatia's family, and Madhu's family all die in a bomb blast. RK's and Madhu’s daughter Jr. Madhu was spared from the blast as she went outside for fresh air. RK and Madhu’s family's death is planned by Pammi Harshvardhan Kapoor and Nikhil Lamba to avenge their insult from Harshvardhan and RK and also to trap and put Harshavardhan Kapoor in jail for killing Rk and Madhu as well as for snatching Harshvardhan's property, RK's property, and RK’s Mansion. Radha escapes with baby Jr. Madhu and raises her away from movie industry and Mumbai but Jr. Madhu is interested in films, dance, music, and dramas like her parents.

Jr. Madhubala is now grown-up and looks like Madhu. She lives with Radha and falls in love with Abhay Kapoor. In RK mansion now Abhay and Kapoor family are residing after the death of RK, Madhu, Kundra's and Bhatia's. They announce their marriage but he gets her married to Raja, RK's mentally challenged second lookalike who is KRK's son.

Abhay reveals he wanted to avenge death of his father Harsh Vardhan who committed suicide after being incriminated for killing RK and Madhu. Actually KRK's son, Raja finally becomes a normal person and also kills abhay kapoor for torturing madhu and him. Due to his life of a gangster, Madhubala hates and insults him. Angry, Raja rapes her. She files a case and gets him jailed but withdraws it later.

Baiji dies. Being jailed, Raja thinks Madhubala is the reason for it and begins hating and torturing her. Pregnant with his child, she later requests him to forgive her which Raja does. They remarry. One night, a producer assumes Raja as RK and proposes to do a film with him that the producer had wanted to do with RK and Madhu.

Madhubala reads Madhu's diary, learning her last wish was to make a film on her and RK's life. She convinces Raja to sign the film; they start their career and appear as Madhu and RK, giving the first shot of their film. Raja states it is not the end but the beginning of a new life as they were always destined to live and be superstars together.
