The story:
When the Phantom is away, a young boy called Toma looks after Hero in a jungle corral. Hero likes to exercise on his own, and one day two hunters spot the great white stallion running at break-neck speed through the jungle. Realising that such a record-breaking horse will make them very rich, they eventually manage to capture both him and Toma and set off for the harbour.

Returning to the jungle, the Phantom finds the corral deserted without any clues where Hero and Toma have been taken. It is not until a stray newspaper article catches the Phantom's eye that the trail suddenly goes hot again...
