S2E7 The Other 48 Days

The gripping first 48 days for the tail section survivors unfold. Flashbacks provide insight into the experiences of Ana-Lucia, Mr. Eko, Bernard, Libby, and others as they find themselves on the beach on the opposite side of the island. As time passes, their camp faces peril when "The Others" begin abducting members of their group. In a desperate attempt to escape, the survivors venture further inland, only to discover that one of them is not a genuine passenger from Flight 815.
