Chandrashekhar (Shammi Kapoor) or Shekhar as he is called now, belongs to an aristrocratic family, who believe laughter is a sign of belonging to the lower class, and as a result laughter is not encouraged in the household, run by Shekhar's domineering mom (Lalita Pawar). In this household the only one who dares to laugh and enjoy life is Shekhar's sister Mala (Shashikala), who also dares to love Jeevan (Anoop Kumar). Things change when their mom finds out about Mala's indiscretions, and she asks Shekhar to take her away from their home, to distant and scenic Kashmir, for awhile. She also instructs Shekhar to arrange to get married to a girl from a princely family. When Shekhar escorts Mala out of town, and on reaching Kashmir, he meets up with beautiful Rajkumari (Saira Banoo), and after being stranded with her for a night during a snowstorm, he realizes what he has been missing, and becomes a care-free man in love. This change is welcomed by Mala, but not by his mother.
