A gang steal explosives to exploit a diamond mine but after killing people Tarzan (Gordon Scott) is on their trail. The gang travel up river towards the mine and Tarzan follows both aided and hindered by a female pilot (Sara Shane) on the track of one of the men (Anthony Quayle) who he knows has previously killed people. Anthony Quayle gives a good performance as the leader of the gang and there is good support from Sean Connery in an early role. Sara Shane does well with the role she has.
