Kal Aaj Aur Kal

Diwan Bahadur Kapoor aims to secure Rajesh's marriage to Rukmani, the granddaughter of his longtime friend. This arranged match is meant to strengthen family alliances and uphold tradition. The plan sets up a clash between the older and younger generations.

Rajesh falls in love with Mona and refuses to bow to his grandfather's scheme. He makes clear that he would lose Mona if forced into the arranged marriage. The conflict between love and duty deepens the family rift.

Ram Bahadur watches the feud between his father and son with growing pain, realizing he is the true casualty of their quarrel. Unable to reconcile the competing loyalties, he leaves the family home. The rift between grandfather and grandson widens in his absence.

Ram's friend suggests a plan: Ram should pretend to stay at a hotel and drink heavily to project a harmless, carefree image. The ruse is meant to soften the immediate pressure of the marriage dispute. It buys time but irks the already tense family dynamics.

The grandfather and grandson appear to have reconciled their differences and celebrate a facade of harmony. They project unity to the rest of the family and friends. Behind the smiles, the underlying tensions remain unresolved.

Ram catches wind of the staged reconciliation and the ruse behind it. Feeling betrayed, he leaves the party in anger. The rift among the three generations becomes even more pronounced.

Diwan falls sick yet expresses a simple wish: to witness his grandson's wedding. He confesses that, apart from this, he is content with the family, if he can only see the union. His vulnerability highlights the emotional stakes of the feud.

Rajesh decides to give up his love for Mona to secure his grandfather's happiness. He informs Mona of his decision, and she accepts, agreeing to attend the wedding despite the heartbreak. The act marks a crucial turn toward intergenerational reconciliation.

On the wedding day, Rajesh seems to marry Laxmi, following his grandfather's wish, yet he remains emotionally torn. The ceremony proceeds under a cloud of unresolved longing and family pressure. Mona's presence elsewhere underlines the personal cost of the sacrifice.

During the ceremony, the bride lifts her veil to reveal that Mona is the real bride. The revelation redefines the sacrifice, showing that love endures even when outward appearances suggest conformity. It reframes the entire wedding as a union built on mutual devotion.

Diwan explains that if he could sacrifice for his grandson, he must also sacrifice a little for Rajesh. The allegory of yesterday, today, and tomorrow is made explicit, stressing that love and duty can coexist across generations. The family begins to understand each other more clearly.

Rajesh scatters his grandfather's ashes, signaling the end of the feud. At the same time, Rajesh's son is born, making Ram a grandfather at last. The film closes with a renewed sense of family harmony across generations.
