“Everyone is looking forward to commencement until shocking news about Carlton threatens to overshadow their special day. Daphne fears her future is in jeopardy when her past catches up with her. John and Kathryn are not happy when they learn about Bay’s non-traditional post-graduation plans,” according to the official synopsis from the network.

“Meanwhile, Mary Beth is pleased when Travis’s wish comes true.”
