A war of generations begins as Millennials battle Gen X.

Millennials and Gen X get physical in the first reward challenge of the season, and two castaways are out for revenge after being blindsided by their allies.

Castaways form a search party to hunt for the hidden immunity idol, and one tribe gets an unpleasant surprise when castaways drop their buffs.

Figgy and Taylor may regret an earlier decision to reveal their budding "showmance" to their tribemates, and some castaways worry there may be a snitch at camp after a hidden immunity idol is found.

Two Millennials attempt to put the past behind them and work together, and another castaway feels the heat when they're interrogated about their true profession.

The season’s first Individual Immunity is up for grabs in a classic challenge. Also, one castaway finds an all-new advantage in the game, while another staves off hunger by stashing food for a rainy day.

Two castaways with secrets about each other use them as leverage in the game, while another refuses to "drop the ball" when individual immunity is on the line.

A power struggle between castaways erupts, and each player tries to arm themselves with allies. Also, tensions rise when castaways from Gen X turn on each other and one castaway throws another under the bus to build trust in the game.

Castaways receive a much-needed reward in the form of love, and one castaway works hard to build their resumé in the game.

It's double the tribal councils as two castaways are sent home, and immunity is on the line in a classic game of Survivor pinball.
