A crocodile never lets go once its teeth grits onto a target. It is this immense tenacity that Croc (played by Kai KO) aspires to possess. Unfortunately, Croc’s misjudged sense of loyalty led him astray and he ended up in jail at the mere age of 17. After getting out on parole, Croc seeks his brotherly figure, Chief Liu (played Kang Sheng LEE), for help and receives employment at his office. Eventually, Croc gets assigned to Zhi Ping Chen (played by Sinje LEE), a young and headstrong farmer demanding answers for the water blockage issues at her farm. It turns out Zhi Ping Chen is the only farmer in the entire neighborhood who refuses to allow her land to get expropriated. Her persistence gave her many problems. With no one else to turn to, she meets the only person willing to help - Croc, a youngster trying to reintegrate back into society. Through their constant bickering and conflicts, they soon find trust and solace in each other’s presence. However, with Chief Liu’s involvement in the water blockage issues, Croc grapples to balance his career and love life. 

A young punk struggling to make his life better meets a strong-willed farmer. Croc realizes he faces a much bigger issue than just the farm itself - having to choose between his career and a girl he loves. Caught in the middle of this cruel food chain, and stuck between a rock and a hard place, can Croc break free from the shackles of society and prove himself worthy of transforming into a powerful crocodile that never lets go of the one he wants to protect?
