Contacto sangriento (1988)

As a child, a miscreant Frank Dux was taken in and trained by a champion martial artist, who went so far as to adopt Frank into his family after the premature death of his own son. Now, decades later, Frank is a skilled martial artist himself and a soldier in the U.S. Military. Upon the death of his surrogate father and sensei, Frank is informed of a mysterious, no-holds barred, highly illegal martial arts tournament in Hong Kong known only as the "kumite." At the bidding of his sensei and against direct orders from his military superiors Frank travels to Hong Kong to participate and uphold his master's honor. In order to succeed not only will he have to win the tournament; he must also evade capture by two military police sent to arrest him and the prying questions of a nosy reporter eager for a story.
