The Mountain of Light, a London Indian Restaurant, is Balu's great love, the delicious kulfis and dansaks he devises in its kitchen his sole connection to the land of his childhood. When a young woman, Sarah, rents the flat upstairs, she, her boyfriend Jude, and Hari, a waiter, begin to gather after hours to chat around Balu's tables, though Jude's jealousy of Hari threatens their circle. Meanwhile Jozef, an elderly Polish man, begins to reveal a heartbreaking story to Sarah, and so inspires a journey that will lead her to discover where - and with whom - she really belongs.
