Walt and Judy's happiness has been blighted by their childlessness; although their marriage seems blissful, Judy feels increasingly empty and Walt longs to make her happy again. So one day he brings home Looee - a baby chimpanzee. Looee, exuberant and demanding, immediately fills up the gap in Walt and Judy's life, and they come to love him as their own son. Like any child, Looee is affectionate and quick to learn, generous and engaging. But he is also a deeply unpredictable animal, and one night their unique family life is changed forever.
