Mumbai, July 6 (IANS) Mithun Chakraborty, the original disco king of Bollywood, will be seen sharing screen space with his 1980s co-star Rati Agnihotri in 'Chal Chalein'. But they won't be seen as sweethearts.

Mithun, who acted with Rati in films like 'Shaukeen', 'Pasand Apni Apni' and the super-hit 'Boxer', among others, will prosecute her in the movie.

'Mithunda and Ratiji are not paired together,' said the director of the film Ujjwal Singh who makes his directorial debut with the social drama. 'While, Mithunda plays a lawyer, Ratiji plays an introvert housewife from Bihar,' Singh told IANS.

Mithun will prosecute Rati and her husband in a case filed against them.

'It is the story of eight students, who find themselves in extreme anxiety because of their parent's constant pressure to excel in their academic career.

'One of them is unable to withstand the pressure and commits suicide. All the seven friends decide to file a case against their dead friend's parents and government.

'The parents of the child who commits suicide are played by Rati and Kanwaljeet Singh, while Mithun plays the children's lawyer. The whole case takes the shape of a national issue and generates a lot of public opinion,' said Singh.

One of the defence lawyers is played by 'Chak De! India' girl Shilpa Shukla and Mukesh Khanna will be seen as chief justice.

The music maestro from south India Illayraja has scored the music of the film.

The film, that has just concluded its shoot, is in its editing stage and expected to hit the marquee sometime in September, Singh said.
