Rising tensions between the Andorians and Tellarites threaten to erupt into open war when their ships are sabotaged during peace talks. Each side believes the other is responsible, and communication quickly breaks down. Captain Archer and the Enterprise crew uncover that the crisis is being deliberately engineered by Romulan agents posing as Andorians. Their goal is to keep the major powers divided and prevent cooperation between species that could one day form a unified alliance. The resolution of the Babel Crisis helps bring Andorians, Tellarites, and Humans closer together. It becomes a key step toward the trust and diplomacy that will eventually lead to the founding of the Federation.
