Synopsis: Time Port

In the distant future, time travel is not only possible, it's commercially viable. The Los Angeles time port sends hundreds of people per day on vacations into the past.
A single slip up could mean the end of history as we know it, so naturally security is tight. But just in case security misses something, the Time Marshals are our last line of defense.
A Time Marshal blends in to a tour group and discretely keeps an eye on them, making sure to put a stop to any anachronistic shenanigans.
