Lee Jung-hyun and Oh Soo-ah are living a normal life as a couple until it is revealed that Soo-ah is actually the daughter of Oh Byung-moo, chairman of SR Electronics, the very company he works at. Shocked and hurt that Soo-ah wasn't honest with him, Jung-hyun tries to break up with her but she convinces him to give their relationship another chance. One night, Jung-hyun is summoned to the chairman's vacation house. Inside, Jung-hyun finds the chairman and the housekeeper both on the floor, the former unconscious and the latter dead. When Jung-hyun attempts to carry the chairman out of the house, a fire is started and Jung-hyun is knocked out. After the evidence points to Jung-hyun as the main suspect, he is sentenced to life imprisonment. To give her son a chance to get out of jail and prove his innocence, his mother kills herself. Cornered by policemen and the SWAT team after a long and exhausting car chase, Jung-hyun jumps off a bridge. Believed to be dead by everyone, he flees to Shanghai, China where he struggles to survive. He suffers much, homeless and begging from strangers or scavenging garbage cans for food. Time passes and he meets a Korean man named Lee Choon-bok who eventually becomes his good friend and guardian who takes good care of him like his own brother and son. He also finds Cha Yoo-ran, the chairman's secretary and ex-lover of SR Director Shin Hyun-tae. Yoo-ran decides to help him after Shin orders some men to dispatch her. Under the guidance of Chen Daren, a Chinese business tycoon whose life he and his friends had saved from an assassination attempt, Jung-hyun develops acute business skills and becomes chairman of Super Digital Enterprise, a large Chinese company. After three years, he, Yoo-ran and Choon-bok return to Korea to help him discover the truth and punish the people who framed him. Soo-ah, who is dating Shin Hyun-tae upon his return, immediately sees through his Zhang Zhongyuan facade and recognizes him as Jung-hyun himself. With the help of Soo-ah, Choon-bok and his best friend Kim Dong-wook, he discovers that Shin is the person who tried to kill Soo-ah's father. Secretly desiring Soo-ah for years, he also framed Jung-hyun to have her all to himself. Director Seo, who witnessed the crime, is the man who had hit Jung-hyun on the head and attempted to kill the chairman as well. In the end, Jung-hyun is able to successfully clear his name and Director Seo and Shin commit suicide. He and Soo-ah happily reunite.
The Philippines produced their own version of this series, which aired on ABS-CBN in 2011. The remake starred Jericho Rosales as Jerome Delgado, Anne Curtis as Angela Tuazon, Jake Cuenca as Edward Fuentebuella and Alessandra de Rossi as Geena Rallos. What's interesting in the names of characters in adaptation is that most of the surnames used here are owned by Philippine scouts who died in their journey to 11th Jamboree, e.g.: Delgado, De Guia, Fuentebella, Reyes, Tuazon, etc.
