Mr Kolderup (Peter Cushing) buys a tropical island for five million dollars. His rival Taskinar (Terence Stamp) also wanted the island - because he knows a gold treasure is hidden there. Still he couldn't make a higher bid than Kolderup. When Kolderup sends young Jeff (Ian Sera) to the island along with his teacher (David Hatton), because the lad looks for adventure, wants to become a man et cetera, Taskinar plans to make that adventure much more dangerous than intended...
