Katrina Kaif's sister Isabel and Salman Khan are a team

Big sister Katrina Kaif may have moved away for greener (or younger) pasture (read Ranbir Kapoor) but little sister Isabel Kaif is still tagging along with godfather Salman Khan.

Isabel is all set to make her acting debut with 'Dr. Cabbie' which is being co-produced by her sister's ex flame Salman Khan.

'Dr Cabbie' features Vinay Virmani, who was appreciated for his work in Bejoy Nambiar's 'David'.

The film set in Toronto, is a heartwarming journey of a young Indian doctor, Deepak Chopra, played by Vinay, who goes to Canada with the selfless ambition of healing others while beginning a new life in the land of opportunity.

The Indian doctor becomes a cabbie as he could not get a job. The film traces the journey of Vinay Virmani, the protagonist, as he turns his taxi into a mobile clinic.

Dr. Cabbie discovers his true purpose and true love when he embarks upon this journey of a doctor turned cabbie.

Katrina's sister, Isabel has been cast opposite Kunal Nayyar, who gained fame for his role of Rajesh Koothrapalli in 'The Big Bang Theory'.

However, this film is not the launchpad for Isabel. If sources are to be believed, Salman and Katrina will produce a project to launch Isabel in Bollywood.

In the female roles, the film has American actor Adrianne Palicki in the lead role, Lilette Dubey, who is playing Deepak's mother and Isabel.

The trailer comes across as a quirky comedy film directed by Canadian director Jean-Francois Poulliot.
