Peih-Gee Law

Twenty returning castaways begin their adventure -- and their second chance -- in the middle of the South China Sea.

The 16 castaways are marooned on two separate islands with only the clothes they are wearing.

A classic immunity challenge leaves one tribe puzzled; a contestant hopes an apology will help stave off an elimination.

The castaways switch from two tribes to three; a castaway is caught sending a message to another tribe.

The castaways participate in one of the most physical and dirtiest challenges ever; one castaway believes that she has received a gift from God.

One castaway searches for the hidden immunity idol while everyone else sleeps; the contestants are confident as they head into the tribal council; one castaway is sent home.
