Eighteen strangers are abandoned on the islands of Fiji with the chance to win million; tribes must claim victory in the grueling marooning challenge to earn essential camp supplies; castaways are chosen to face off with a huge reward on the line.

Reality and hunger begin to take their toll as the castaways grapple with their limited resources to find food on the island. Generational differences come into sharp focus as some castaways find it challenging to keep up with the younger players' current lingo. Then, a never-before-seen disadvantage appears in the game during this week's immunity challenge.

An unprecedented medical emergency leaves the castaways shaken. A second beware advantage is found in the game, and its finder must earn their vote back before it's too late.

An unexpected shakeup shifts the castaways' game trajectories in an all-new direction. Teammates must rely on one another to succeed in a grueling immunity and reward challenge. Then, a wild goose chase unfolds to reinstate one castaway's vote after the discovery of a beware advantage.

One castaway's scheming gets them into hot water when their tribe realizes the same conversation has been repeated to each of them. Two castaways are sent on a grueling journey. Then, one castaway's series of missteps leaves one of their tribemates hungry for revenge.

A major shakeup hits the game when two tribes turn to three. New tribe members size each other up, but with only four players on each tribe, there is not much room to hide. Then, heat and exhaustion take a major toll on one castaway.

A boat arrives delivering a very important message to the overjoyed castaways. Old alliance members reconvene to talk strategy, as the game has shifted since they last saw each other. Then, the game intensifies when a two-part challenge leads to the season's first individual immunity win.
