Review –
Over the last couple of years, I have discovered that I really enjoy a good
sports film. There are the great highs, and deep lows, as great talent is on
display. Today we are looking for a film out of Hong Kong about the world of
MMA and the struggle to be the best, based on the life of Dixin Xiong.
So to set the scene, we open with Bunny (Yiu-Sing Lam) as he rushed from work
to an underground fight ring. He is asked by his friend to throw the match, but
that is not something he can do. Upsetting a bookie, Bunny has to lie low so he
goes back home, where he left on not great terms. As he walks in his brother
Jack (Edward Ma) is give a press conference as he is about to fight Jason Chan
(Jason Li) whose arm Jack broke last time they fought. There is a lot of
tension because even though their adoptive father Eric (Eric Kot) and his
sister Simo (Qiu Yuen) are happy to see Bunny, Jason is not.
