I added to the gallery the promotional stills from the episode 1×04: Chadwick’s Angels of Making History, also you can read below the official synopsis:
In need of a victory, the trio heads back to the 1990s to give Dan another shot at his childhood dream: finishing the infamous “Bellybuster” ice cream sundae at a local parlor. As Deb bonds with the parlor’s owner, Chris is on a mission to save a life in honor of his late British friend. But all of their plans are derailed when Dan runs into the bully that tormented him.
