It’s been a long summer vacation for television at large. But as the season turns to fall, Survivor school is in session.

For Island of the Idols its 39th season, the award-winning reality show is hosting what host Jeff Probst refers to as a “Survivor boot camp.” The twenty new castaways will be periodically mentored by two legends of the game in previous winners Sandra Diaz-Twine and Rob Mariano. In a game that’s consistently changing, these are lessons that could mean the difference between one million dollars and a snuffed torch.

The clip above depicts the opening minutes of the 90-minute Island of the Idols premiere, airing September 25 at 8 p.m. on CBS. It focuses on the two mentors and gives a sneak peek of how the titular twist will work. Obscuring the actual visitors to the island, we see Rob and Sandra sit down with them to talk through several Survivor lessons, including the art of perception, calculated risk, and staying calm under pressure.

They then present an opportunity to apply their learning to win various advantages. The montage shows one written on a scroll and another as an outright idol, holding true to what Probst and executive producer Matt Van Wagenan told Parade preseason about the twist’s incorporation of variety. Who will be able to take the lessons learned and use them to get to the head of the class? And who will pay the price when their risks come up short?
