James's first annual captains' training brings him out of North County and into Boston for what he thinks will be two days of wasted time. And his opinion is only solidified when the Foundation for Paranormal Studies springs a practical training session on them in the form of a scavenger hunt along the Boston area's public transit lines. But when injuries occur along the line and the Foundation stops answering questions, James and his colleagues start to question if this is a simulation after all.

Matters aren't helped when a simple congratulations note sends James into an existential crisis, questioning everything about his life and career. But maybe he's just overthinking when his focus needs to be on the task at hand. Is this training session an elaborate project set up by the Foundation for the captains' benefit? Or is there something else going on?
