A group of school children are on a steamer bound for Goa-GHANSHYAM, the son of a businessman, and his sister REKHA; RUSTAM POONAWALA, a Parsi boy, and his sister ZARIN; the heavyweight Goan boy SAMMY BRAGANZA and his little sister MARY, the youngest member of the group, QASIM ALI JAFFERBHAI and his sister HUSNA; GOPAL SINGH NIRULA, a Sikh boy; JAMOO GYANCO, the son of a Bhil; DIPAK PRABHAKAR, a Maharashtrian; NARAYEN DEVANPALLI, a Telugu boy who has been raised in an orphanage; and SONOO PAWAR, the son of a blind cobbler, who polishes shoes to pay for this education.
It is this motley group of children that finds itself marooned on a desert island where they have to make a world of their own, while waiting to be rescued.They have various thrilling adventures on this island. But their biggest adventure is to provide themselves with a shelter which they name HAMARA GHAR.
A wordy quarrel between Qasim and Dipak develops into a regular riot, and Sonoo's presence of mind saves Ghanshyam and Rustam, the two eldest boys, from fatally injuring each other. Then, frolicking in the sea-waves, Sonoo is drowned but is saved by the daring of Ghanshyam.
But then Ghanshyam discovers a hidden treasure of jewels and a couple of rusty swords, and proclaims himself the king of the island. For time he and his henchmen exploit the labour of the other children but eventually they are not disarmed but literally 'disrobed', and brought back into the brotherhood of children.
Once again the sky is full of planes. Once again the children shout aloud their pleas to be rescued. When no plane seems to heed them they feel frustrated and bitter. In a moment of blind anger they want to destroy what they had jointly created, but in that very moment help arrives in the shape of a helicopter.
As they fly away to rejoin their families, "Hamara Ghar" continues to stand on that desert island-a symbol of national integration.
