The Second Chance finale is just a week away, and the final seven competitors struggled to stay afloat (literally) as episode 13 put them through their paces. Read on to find out who snagged a temple feast and who gained this week's immunity.

The episode kicked off with a Rewards Challenge from San Juan del Sur. The real trick to this endeavor was spooling out enough rope. Those who didn't give themselves enough slack couldn't make it through the obstacle. Keith handily won the round and he selected Kelley and Spencer to join him at the temples of Siem Reap.

It was the Immunity Challenge, however, that really proved to be the hard part. Set on a ocean obstacle course, the task required players to dive under water to retrieve a key. Once back on land, the survivors would use the key to unlock a puzzle and gain immunity. Spencer quickly won the round, but all eyes were on Tasha as she floundered in her search for the key. To keep her out of harm's way, the safety team jumped into action.

Despite Tasha's mishap, it was Ali who was voted off.
