Bossam was a custom in Joseon period, in which a bachelor, who missed marriage secretly wrapped up a widow in a blanket at night and made her his wife. This custom changes the fate of Ba Woo when he kidnaps a princess by mistake.

Under the rule of King Gwang Hae, widows of the Joseon Dynasty were often stolen in the night and forced to marry their kidnapper, against their will. This practice, known as bossam, was a customary practice employed by those wishing to easily gain a wife and there were those, like Ba Woo (Jung Il Woo) who made their living, stealing these widows for other men. Framed for a crime he didn't commit, Ba Woo was forced into hiding at a very young age. Barely escaping with his life, he was forced into hiding. Growing up in abject poverty Ba Woo got by as best he could. Now a scoundrel and a degenerate, with a nasty gambling habit and a penchant for picking fights, Ba Woo wasn't the marrying type himself; but he had no qualms about stealing widows for other men. Often hired for bossam, Ba Woo never had any troubles stealing a wife, at least not until the day he accidentally kidnapped the widowed princess, Soo Kyung (Kwon Yuri). Now stuck with the daughter-in-law of his sworn enemy, Ba Woo finds his life taking an unexpected and increasingly complicated turn. Will he be able to free himself of Soo Kyung and return to his old life, or will the presence of a princess lead him down a different path? A tale of mistaken identities and unexpected love, "Bossam: Steal the Fate" is a 2021 historical romance drama directed by Kwon Seok Jang.—Rakuten Viki
