After delivering Belle to the Sky People and after months of trekking home through the jungle, Maria discovered she lost had everything including the laboratory and university funding. In despair and looking to restart her career, she returned to Rio de Janeiro. Santo too lost everything. When returning to his villa, because of his long absence, his family left him. While searching for his twin daughters, he returned to his duties with BASIC.
When BASIC captured a Japanese woman who escaped from the 'Garden of Man', Santo and Maria were once again united to solve the mystery of the strange maps she drew. They were eventually led to Earth Tunnels that within steps transported them to places around the world including deep inside a secret chamber within an Egyptian pyramid.
Unintentionally, for they were two different people, both fell into a web of love.
