I Witness is a 2003 American action thriller film directed by Rowdy Herrington, starring Jeff Daniels, James Spader, Portia de Rossi, Clifton Collins Jr. and Wade Williams.

While there, he becomes embroiled in the investigation of a mass murder in what appears to be a drug runners' tunnel on the Tijuana/San Diego border, which was casually discovered.

He teams up with a local honest street cop and a US official all under the watchful eye of State Department attache, eager to pin the killings on a drug cartel.

But when Rhodes links the human rights atrocity to the murder of two American teenage dirt bikers and discovers they all have been poisoned with chemicals, he uncovers a web of corruption between the US corporation, who owns the factory, and the local police, only to realize that he himself has become a dangerous liability to those who pull the puppet strings on one of the world's most dangerous borders.

Originally entitled "God's Witness," the script is by Colin Greene and synthpop musician Robert Ozn.
