Rescue is finally at hand for the survivors of Oceanic 815, but first someone must reconnect an underwater sonar beacon. Despite his foretold death, Charlie volunteers.

This episode promises a Jack revelation of legendary proportions! Also, there will finally be an en masse collision between the beach folk and the Other's.
