Barry and Iris' relationship is going through a bit of a stand still and both wonder if this is really right for them, and Barry wonders if he should tell her who he really is. At the same time, a bunch of supervillains that Barry has fought before have teamed up and are looking at the biggest score of their lives, and Barry has to figure what they're really up to before it's too late. With all of this going on, Barry meets a young boy who will eventually change his life forever in many different ways, Iris' nephew, Wally West.
