The 30th season will feature the first-time theme of "Worlds Apart", with castaways divided into the three separate tribes, White Collar, Blue Collar and No Collar. Minutes into the game, castaways are forced to choose between honesty or deception, and one castaway becomes ill after trying to satisfy his need for protein.

White Collar castaways strip down and embrace their free-spirited "no collar" tendencies. Blue Collar castaways disagree when it comes to heavy lifting at camp, and one castaway struggles to adapt to her new tribemates.

A division of labor causes cracks in the hard-working Blue Collar tribe. Also, one castaway's strategy during the Immunity Challenge completely backfires.

One castaway struggles after receiving a blow to the head during a reward challenge for chickens. Another castaway's desire to flex his power in the game could be his greatest weakness.

The three tribes merge into two and the castaways move to either changing allegiances or strengthening existing ones.

One castaway struggles to fit in after a shocking Tribal Council. Also, winning a reward gives one castaway a new outlook on life and the game.

Alliances are tested as castaways must adapt to playing an individual game after the merge. Also, castaways fight for Individual Immunity in a classic game of endurance.

Castaways walk a fine line and struggle to stay balanced at a Reward Challenge. Also, one castaway goes on a crazy man hunt to prevent another castaway from finding the Idol.

One castaway breaks out their arts and crafts skills to create a fake Idol and makes a plan to prevent being eliminated.

A key advantage gives one castaway a game-changing opportunity, and another castaway lashes out when their integrity is questioned.

A twist at the immunity challenge creates a two-way race for security in the game, and one castaway uses his entire body as a bridge during a reward challenge. Also, a crazy tribal council becomes confrontational.

A reward gives castaways an opportunity to deliver supplies to a local orphanage. Also, castaways must scramble after a crazy Tribal Council leaves some on the outs.

With only six castaways left in the game, immunity is more important than ever. Also, castaways are puzzled at a tough reward challenge and a strong alliance begins to crumble.

After 39 Days, one castaway will be crowned Sole Survivor and take home the million dollar prize. Also, emotions run deep when castaways receive a surprise visit from their loved ones.
