The story begins as Ashoke and Ashima Ganguli, a young Bengali couple, leave Calcutta, India, and settle in Central Square in Cambridge, Massachusetts. Ashoke is an engineering student at the Massachusetts Institute of Technology (MIT). Ashima struggles through language and cultural barriers as well as her own fears as she delivers her first child alone. Had the delivery taken place in Calcutta, she would have had the baby at home, surrounded by family. The delivery is successful, but the new parents learn they cannot leave the hospital before giving their son a legal name.
