Some strange signals have started coming from Wela Volcano which are interfering with the process Lusamine uses to track the Ultra Wormholes so she sends the Ultra Guardians to Wela Volcano to investigate. However, instead of finding more Ultra Beasts, they instead find a group of rock hunters with an Alolan Geodude and Graveler who appear to be illegally mining Spark Stones, the food of the local Rock Pokémon. Meanwhile Eevee and Mantine are travelling together and having a great time. (Source: Wikipedia)
