Travelers Episode 1.02 Protocol 6

On the team's first mission to stop a shipment of antimatter from exploding and killing thousands of people, things don't go as planned. The truck transporting the antimatter is stopped and they transfer it to containment device for safekeeping. They replace it with an explosive device that is set to explode and cover up the theft.

The mission was supposed to be a simple handoff to another team of travelers, but the contact dies just after the mind transfer. This delays the transfer and they need to extend the time they can hold the container before it goes critical. The upgrade fails and shortens the time so they need to figure out another way to store the antimatter. They devise a plan to return the antimatter to the plant it came from. With the help of the scientist who created it, they are successful.
