Taiwanese high school basketball enters its golden era as Tu-ba Wang and Kuang-Hsu Kao, two superstars under the spotlight, emerge from junior high basketball.
At the same time, two inconspicuous and idiosyncratic players also make their appearance. Small in size, Lai-feng Jen is a forward who is fierce and defiant despite losing every single game in the junior high league. Remarkably tall, Yun Liu is a point guard who's both talented and disciplined, yet still stuck as a substitute player. The two first meet at a game in the junior high league, and cannot seem to stop running into each other.
During a national broadcast, Lai-feng Jen publicly challenges Tu-ba Wang to a game in the high school basketball league (HBL). Yun Liu retrieves his competitive spirit, refusing Kuang-hsiu Kao's invitation to join his team and becoming his rival instead. After graduation, Jen and Liu receive invitations from Elena, the "basketball queen," to join the team at Huo-Shui High, which seeks to return to its past glory in the HBL. They befriend other freshmen players, each with unique personalities.
Together, the problem students of the Huo-Shui High basketball team form a fighting dog legion that others mockingly call "drowning puppies." They resolve to win the once-in-a-lifetime Taiwanese High School Basketball League Championship, defeat superstar players, and become great players!
Once the ace player of the Fen-Chi Junior High basketball team, now a freshman on the Huo-Shui High basketball team. A forward, he is full of energy. He's short but jumps amazingly high. He's quiet and straightforward, and a great booster for the team with his fierce spirit and vital perseverance. His trademark play is the legendary NBA move “Skyhook.”
Once a substitute point guard for Yang-Ming Junior High, a school famous for basketball, now a freshman on the Huo-Shui High basketball team. He is tall and thin and passes balls like a magician. He considers himself a genius who is able to lead his team to the championship but is defeated by star player Kuang-hsiu Kao and demoted to substitute. After playing with Lai-feng Jen, he retrieves his competitive spirit.
