On the special occasion of Kajol's 44th birthday, the makers of Kajol's film, 'Helicopter Eela' decided to unveil its trailer on that day, which is Sunday, August 05. The film has Kajol play a new-age and free spirited single mother to a son, who joins his college to complete her education. Kajol is phenomenal playing the character of a quirky yet an over-protective mother, which leads to differences between the mother and son's relationship. She also aspires to be a singer.
