Scooby and the gang experience outdoor fun as they go back to Fred's old summer camp. As summer goes on, it becomes increasingly clear that the spooky camp stories told by the fireplace, are more real than they've though and soon, it's up to the gang to try and solve the mystery of camp scare.

Reverse-Flash manipulates the Speed Force to put the Flash into a time loop that forces him to relive the same day over and over again—with progressively disastrous results, including losing his powers and being fired by the Justice League. The Flash must find a way to restore time to its original path and finally apprehend his worst enemy before all is lost for the Flash…and the world!
