Former Formula 2 driver Morita, known as 'Kamikaze Run', is asked by Onodera, an old friend and current representative of a large trade company, to function as intermediary for an auction of vintage cars owned by Morita's former rival Gianpiero, until an accident ended both careers. Onodera invites Morita to stay in his house until the auction, but his wife seems to have a past connection with the guest, while his son takes a huge liking to him, to Onodera’s raising frustration on both fronts. Meanwhile, his wife’s younger sister has a relationship with a young driver, while Onodera cooperates with billionaire Kurosawa and Morita’s ex-lover, Kyoko, in order to rig the auction.
