An espionage thriller with a metaphysical twist, Counterpart tells the story of Howard Silk (Simmons), a lowly cog in a bureaucratic U.N. agency who is turning the last corner of a life filled with regret, when he discovers the agency he works for is guarding a secret: a crossing to a parallel dimension. Through Howard and his “counterpart” on the other side, the show will navigate themes of identity, idealism, what ifs, and lost love.
