Dia's family is all set to go to Switzerland for summer vacation, but she is not excited. She has a trail of questions in her mind like why she feels a void despite having a loving family, health and required wealth. What is the purpose of her life? Where did she lose that connection with the Almighty? Why does she have some fears and concerns for her son? Why does she feel stuck in life? Why does life appear to be stagnating?...

Aditya gives her the hope that she will get all her answers during their upcoming trip to Switzerland.

'Sunshine' is all about how Universe arranges synchronicities and brings right people, at the right time, at the right place to reveal the answers.
