Watch Tough Guy

The story is about a pair of cops (Chen Sing and Chang Lik) who are tasked to stop drug runners. Chen goes undercover as a prisoner to help break a gang member out. He ingratiates himself to the gang and with Chang staying near but out of sight, gets to the bottom of it. Unfortunately, Chen's ruse is discovered and he is captured and beaten. He escapes just in time to stop the latest shipment and a fierce battle ensues, ending with Chen and the gang's number one enforcer battling it out in the mud. Great old school knockdown, drag out action to be found here.
