When the rest of the kids at school break up for their summer holidays, Masao (Sekiguchi), a young lad who lives with his grandmother, finds himself home alone. With nothing better to do, he sets off to visit his estranged mother in Toyohashi, whom he has not seen since he was a baby. Meanwhile when Kitano's clueless reprobate, the unemployed mobster wannabe Kikujiro, finds himself hanging around at a bit of a loose end too, he is sent off packing by his wife with 50,000 Yen in his pocket to escort the young scamp and make sure he is delivered safely.
