In this clip from Sunday's show, which is exclusive to The Hollywood Reporter, the final four compete in what host Jeff Probst describes as "an advantage in the final immunity challenge" -- and one player takes a spill.

The two-hour season finale (8:30-10:30 p.m. ET/7:30-9:30 p.m. CT/8-10 p.m. PT) will be followed by a live hourlong reunion show (10:30-11:30 p.m. ET/9:30-10:30 p.m. CT/10-11 p.m. PT).
