An international terrorist who avoids NTSF capture by staying out if their jurisdiction is finally corned on a cruise ship... or is he? Trent goes rogue and pretends he's taking the NTSF team on vacation in a ruse to bust this evil man in international waters. But there's a kink when Piper brings her fiancee on the cruise without informing him of her secret identity.

A particle accelerator malfunction sends Trent into an alternate universe where NTSF is a peaceful organization and terrorism is extinct. Now Trent and his parallel-world doppleganger must restore the time line and the natural order of violence.
