Kidnappers from the Future

The time travel program is expanding with the addition of Dr. Sam Weiss's niece, Samantha Weiss. Before she can even get on base, however, she, her uncle, and Special Agent Hessman encounter a group of Russian terrorists that vanish into thin air, leaving behind a strange type of electrified bullet that no one has seen before. The mystery deepens when later, despite all security precautions, the terrorists once again appear, this time right in the middle of the base, and kidnap Samantha away to parts unknown.

With security footage now of the kidnappers and their strange devices in action, along with some tweaking of the temporal scanners by Dr. Weiss, it is determined that these Russians are actually from the future. Why they would want to come back and take Samantha is one of the mysteries set before them as General Karlson orders the team on a mission to the future. Their orders: rescue Samantha and find out why she was kidnapped in the first place.

Besides the difficulty of going into a future where their primitive tech is as outdated as vacuum tubes, there is another complication-it seems as though Special Agent Hessman is falling in love with Samantha.
