Shinya Ban (Masao Wakahara) returns from the south and is deeply disappointed when he learns that his mutual friend Yuriko (Mieko Takamine) is marrying Toshio (Toshio Hosokawa), the son of Zenpei Hamaguchi (Yoshito Yamaji), for her obligation. He encouraged the unhappy Yuriko and taught her how to make her marriage with Toshio a happy one. He makes a fresh start as an architect under the care of Ryosuke Shibata (Jiro Yanagi), who had taken care of his father, but Ryosuke's daughter Sumiko (Yoko Katsuragi) has feelings for him. Fujie Kakimoto's (Sadako Sawamura) son Koichi (Eiji Wakasugi) came to know about Sumiko and asked her to marry him after coming to Shinya to ask for her design. Knowing that Shinya's love for Yuriko would not be easily wiped away, Sumiko decided to marry Koichi, who had a bad leg. Shinya watches the beautiful bond between Koichi and Sumiko and decides to forget his past and move forward on the path to self-perfection.
