Stan was delivering medicine to Joule Town for a sick child in his ambulance. However, there was a lightning storm brought on by Zapdos, and one lightning strike loosened a boulder. As a result, he crashed his ambulance after swerving to avoid the boulder loosened after it fell. With his ambulance out of commission and his leg injured, he was forced to take shelter in a nearby cave, which Ash and his friends subsequently came across. He asked the group for help in delivering the medicine, explaining that the cave is also a shortcut to Joule Town but became blocked from a rock-slide some time ago.
Stan was later escorted to town by Ash's friends, where he received medical attention from Nurse Joy and was stated to be on the way to a full recovery by the end of the episode.
