The U.S.S. Enterprise transports Vulcan Ambassador T'Pel aboard from the U.S.S. Zhukov, and takes her to the Romulan Neutral Zone to negotiate with the Romulan Empire. However, as she is beamed to the Romulan Warbird Devoras, her pattern disappears during transport.
The Enterprise crew determines that the Romulans transported T'Pel aboard the Warbird with their own transporter, to make it look like she was killed in a transporter accident. When the Enterprise confronts the Romulan Warbird Devoras, a second Warbird decloaks, and the Romulans reveal that Ambassador T'Pel was really Sub-commander Selok, a Romulan spy. As three more Warbirds enter the sector, the Enterprise returns to Federation territory.
