The two Wallace Brothers have arrived in Singapore on the yacht, Silver Spray. Together with Singaporeans, Kheng Peng and Zainal, they go in search of the fabulous treasure of General Yamashita, 'The Tiger of Malaya'. The Silver Spray takes them first to Pulau Tulai in the South China Sea. However, an unexploded bomb, a shark, a tsunami and an underwater earthquake all try their best to foil the boys.
