Sangam

Sundar, Radha, and Gopal have been friends since childhood. As they grow into adults, Sundar develops an obsessive romantic attraction to Radha, seeing her as the only woman in the world. Radha remains wary and prefers Gopal, who also loves her.

Sundar is the confidant Sundar turns to about his feelings. He decides to sacrifice his own love for his friend's sake, prioritizing Sundar's happiness and their friendship. The trio's dynamic becomes a delicate balance of loyalty and unspoken longing.

Sundar enlists in the Indian Air Force and is assigned a dangerous mission to Kashmir to deliver supplies to frontline soldiers. Before departing, he extracts a promise from Gopal: never let any man come between Radha and Sundar while he is away. Gopal agrees, concealing his own deeper feelings for Radha.

Sundar completes his mission, but his aircraft is shot down over Kashmir, and he is listed as killed in action and presumed dead. He is awarded the Param Vir Chakra for bravery, a recognition that fills Radha and Gopal with both sorrow and pride. The news reshapes their lives and the future they had imagined.

News of Sundar's death saddens Radha and Gopal, but they begin to move forward with their lives. Meanwhile, Gopal writes an unsigned love letter to Radha, the words stirring her and becoming a private keepsake she hides away. The letter's existence hints at what could have been, hidden beneath routine grief.

Sundar returns alive and well, and Gopal steps back again to keep the peace for his friend. The reborn Sundar resumes his courtship of Radha, and the two begin to plan a marriage. Gopal's quiet self-sacrifice continues to shadow their life with unspoken tension.

Radha and Sundar marry after Sundar is awarded the Param Vir Chakra, eventually earning her parents' reluctant approval. The new couple enjoys a period of happiness, even as the memory of Gopal's sacrifice lingers. Gopal remains a supportive friend, never quite stepping out of the shadows.

The couple returns from an extended European honeymoon and savor the dream of a perfect life together. Yet Sundar's devotion to including Gopal in their lives unsettles Radha, who resents being used as a middle ground. The tension between friendship and marriage intensifies behind the smiles.

Sundar accidentally discovers the unsigned love letter Gopal wrote to Radha, the discovery shattering the fragile trust in their marriage. He reacts with jealousy and anger, pulling a pistol on Radha and demanding the identity of the letter's author. Radha refuses to reveal the name, insisting on her own autonomy.

Radha flees to Gopal for sanctuary, hoping to escape the torment of Sundar's jealousy. Sundar, unaware that Radha has sought Gopal, pursues them, pulled by a need to control the narrative. The confrontation culminates in the truth about the letter.

Gopal admits writing the letter, acknowledging that his hidden affection nearly destroyed their friendship. Sundar asks why he sacrificed his chance at Radha, admitting he would have done the same for Gopal. Radha chides both men for treating her feelings as collateral damage.

With no escape from the impasse, Gopal takes Sundar's pistol and shoots himself, ending the dangerous triangle. Sundar is left to grapple with betrayal, loyalty, and grief. Radha's heart aches for the two men and the life they could have shared.

Radha and Sundar are finally reunited, but their happiness is tempered by mourning for Gopal. The three friends' story closes with love surviving alongside sorrow, as Radha and Sundar begin a new life together in memory of their friend. The resolution emphasizes the cost of friendship and the endurance of devotion.
