In response to the growing use of sophisticated digital encryption to conceal potential threats to the United States, the National Security Agency has ushered forth the new dawn of intelligence-gathering techniques. The top-secret initiative is dubbed Third Echelon.

Its existence denied by the US government, Third Echelon deploys a lone field operative. He is sharp, invisible, and deadly. He has the right to spy, steal, destroy, and assassinate to protect American freedoms. His name is Sam Fisher. He is a Splinter Cell(tm). Sam Fisher works alone. But fights for us all.
