A man on a train is looking out of the window. The train is travelling across India, heading South, to Kerala. The man is an ex-convict, his name is Samundar Singh. In his youth, caught in the trap of religious fundamentalism, he committed an awful crime. Through his voice and recollections, his story slowly unfolds.

Central India, prison of Indore, year 2002. Samundar is serving a life sentence: he has killed a young Franciscan missionary, sister Rani Maria, with 54 stab wounds. An elderly man, white-haired, barefooted and dressed in a dothi and a shawl, warmly embraces him: “God has forgiven you”. In spite of appearances, the Indian sannyasi is a Carmelite priest, called Swami Sadanand.

While in jail, abandoned by his wife, parents and friends, Samundar was forgiven and helped only by the family of his victim. He remembers the day when Selmy  – Rani Maria’s younger sister – came to celebrate with him the Hindu rite of Rakshabandan. Selmy tied around his wrist the rakhi, the bracelet which symbolizes the bond of sacred brotherhood between a man and a woman. From that moment, Selmy, a Christian nun, and Samundar, a Hindu, are brother and sister.

After the Rakshabandan ceremony, with Swami’s help, Rani Maria’s family asked the Madhya Pradesh Governor to free him from jail. Samundar was released in 2006.

Samundar is now living in his native village, but he feels lonely. No woman will marry him because of his past. He lost his only child while he was in prison. He lives a simple life, working in the family fields and cooking his own meals. He does his best to help others, following Rani Maria’s example and Swami's spiritual guidance.

Samundar visits his sister Selmy at the convent before starting his journey by train to Kerala, where he will meet Rani’s mother and brothers. The only thing that matters for him now is the love of his new family. The mother’s embrace will be for him the start of a new life: “You are my son, I'm glad that you came”.
