Red Chillies Entertainment, Dharma Productions and Hope Productions'Â Dear Zindagi is a story about a girl who is suffering from depression and her fight to overcome the same.
Kaira (Alia Bhatt) is an upcoming cinematographer who wants perfection in everything at work. After having shot many short films and ad films, she harbours the dream of directing a full-length feature film one day. Her dreams seem to take shape when her boyfriend Raghuvendra (Kunal Kapoor) offers her to jointly direct a film abroad. As luck would have it, Kaira's excitement does not last for long as Raghuvendra gets engaged to ex-girlfriend, thus leaving the helpless Kaira to fight her loneliness all by herself.
Just as when hopes seem diminishing for Kaira, she meets the lovely and lively psychiatrist Dr. Jehangir Khan aka Jag (Shah Rukh Khan). An initially reluctant Kaira gradually pours her heart out before Jag. Even before she could realise, Kaira falls in love in Jag, who is already a divorcee with kids.
What are Kaira's problems that deprives her off her sleep, does she get a solution from Jag, what happens to her relationship with Jag and whom does she ultimately settle in her life with, is what forms the rest of the story.
