'Ramchand Pakistani' is derived from a true story concerning the accidental crossing of the Pakistan-Indian border during a period (June 2002) of extreme, war-like tension between the two countries by two members of a Pakistani Hindu family belonging to the 'untouchable' (Dalit) caste, and the extraordinary consequences of this unintended action upon the lives of a woman, a man, and their son.

Belonging to one of the lowest castes in Hinduism (one of the "untouchables"), the family is also part of a small minority of Hindus in a country, which is the Islamic Republic of Pakistan, in which 97% of the people are Muslims. The boy and his father are held captive in India where, in contrast to Pakistan, the overwhelming majority of about 80% comprises of Hindus.

The film portrays the lives of a family that is at the bottom of a discriminatory religious ladder and an insensitive social system, which is nevertheless tolerant, inclusive and pluralist. The irony is compounded by the fact that such a family becomes hostage to the acrimonious political relationship between two neighbor-states poised on the brink of war.
