Mike, a former France Boxer, decided to move to Thailand to turn his life around and start a new life. However, upon arriving in Thailand, Mike was robbed of all his possessions and left with nothing. Desperate, Mike stumbled upon Yo, a talented Thai boxer, and his wife Katoon, who was crippled from a previous car accident.
Mike quickly became friends with Yo and Katoon, and they introduced him to the underground fight club called "Fighting Fish." Despite the dangers, Mike was drawn to the allure of the brutal fight club and decided to participate.
As Mike began to win fights in the club, he gained respect and made money. However, he quickly realized the true cost of his newfound success as his fellow fighters began to die off due to the high stakes of the battles.
Amidst the chaos of the fighting, Mike found himself falling in love with Katoon and vowed to protect her from harm. As tensions rose and the stakes became even higher, Mike, Yo and Katoon found themselves pitted against one another in a final battle, with only one of them surviving the deadly game of "Fighting Fish."
