S3 E5: Three unsolved cases from different eras are suspected to be connected to Joshua’s Trumpet -- originally found by H.G. Wells during Warehouse 2. The ancient ram’s horn connected to a rocket was invented to pulverize anything in its path, but the artifact’s range of destruction does not fit with the most recent victim, who vaporized into ash with nothing sighted within 20km -- it’s been modified. Pete, Myka and Wells revisit one of the old cases and find a kid’s comic book left at the site, and conclude the artifact must have been stolen by the son after witnessing his father’s death. Fast forward to an isolated satellite station, a disheveled man is plotting the coordinates to launch a rocket that is headed straight for a packed baseball stadium -- and in his own delusion, hopes that this will help bring his father back. With three generations of Warehouse agents unable to stop the rocket, will Warehouse 13 be the ones to finally succeed?
