Danny and Ally make a shocking discovery and begin to wonder just what kind of a man Jesse may have become. Pru reaches a crossroad when Slade offers her an interesting proposition and a young man comes to Mark in search of help. But Mark is thrown into turmoil when he realises his closest friends have been lying to him.
When they were twelve years old, Mark, Pru, Danny and Slade were out together in the park. Mark's five-year-old brother, Jesse, was annoying them. They were mean - told him to get lost. Jesse ran away. He was gone. Never seen again.
Twenty years later, Danny - now a detective - learns some shocking news. Jesse's DNA has been found at a murder scene. He is alive and out there. Somewhere.
