Pamela struggles with what to do now that she knows Cliff didn't really kill J.R., and Bobby seeks the aide of an old flame Tracey McKay to help get back control of the company.

And Elena is pushed to the brink when she finds out the real depths of Nicolas' betrayal. As the season comes to an end, enemies are unmasked, new alliances are formed, and John Ross learns a shocking secret about J.R. that sends him halfway around the globe in search of a surprising new cohort.
