A hidden Immunity Idol will finally be played at Tribal Council during next week's episode of CBS's Survivor: San Juan del Sur.

Should 'Survivor' Season 30 Feature 'All Stars,' Newbies Or Another Concept?

CBS has released a plot synopsis for the next episode of Survivor, titled This Is Where We Build Trust, revealing that an idol will come into play.

"Another castaway trades their reward for security in the game," the plot synopsis reads. "Also, the first idol of the season comes into play during a chaotic Tribal Council."

'Survivor': Will Natalie & Reed Now Work With Alec, Keith & Wes As Alliances Are 'Up For Grabs'?

Hidden Immunity Idols have remained hidden through the entirety of Survivor: San Juan del Sur. John Rocker had one the night he was voted out but he was blindsided and did not play it. Keith Nale stumbled upon an idol early in the pre-merge as well but he has held onto it, refusing to play it even when his name was thrown out as a potential target. Now Jon Misch has an idol as well.

It remains to be seen who will play the idol or if Jon or Keith might give the idol to someone in order to protect them before the next vote. Alliances have shifted yet again after Wednesday night's unexpected blindside of Jeremy Collins, so it's anyone's guess who might be playing it.

As it stands now, Jon, Jaclyn Schultz, Missy Payne and Baylor Wilson are in a tight alliance, with Natalie Anderson as a free agent, now betrayed by this group. Reed Kelly joined the two couples in voting out Jeremy, but he could switch back to Keith, Wes Nale and Alec Christy, based on the new sneak peek clip released by CBS.

Survivor: San Juan del Sur airs Wednesdays at 8 p.m. ET/PT on CBS.
