A Handful of Water.

Jürgen Prochnow (Das Boot, Dune) stars as Konrad, an old man still mourning his wife's death, living alone in a large house with little but a tropical fish tank for company. Then he meets 12-year-old Thurba, a Yemeni refugee avoiding resettlement to Bulgaria, after she breaks into his basement in search of food. Her dream is to get to London to find her uncle, and Konrad has to decide whether to help her.
