The school year is finally coming to an end and all that stands in their way of being free from Gossip Girl is graduation day. But Gossip Girl is not one to disappoint and sends out a text during the ceremony giving them all titles (example Chuck – Coward). Serena has had it and is determined to unmask Gossip Girl once and for all. Meanwhile Jenny has to decide if she wants to attempt to become the next queen. Part of her says no but she also knows the only way to stop the cruelty is if she does take over the throne. Blair has to decide if she wants to tell Chuck she broke up with Nate and possibly take another chance on him. But nothing can prepare them for what Gossip Girl has in store for them all, a final blast of gossip as payback for Serena trying to figure out her identity.
