A Line in the Sand on AllMovie

English agriculture equipment salesman Gavin Hughes (Ross Kemp) is recruited by a British-U.S. intelligence agency to report what he learns during a business trip to Iran. His information is used to blow up a bus carrying 24 of Iran's scientists working on weapons of mass destruction. Needless to say, the Iranians are pretty upset with Gavin. Once back in England, Gavin is compelled to leave his (cheating) wife and son, and assume a new identity in a different town. Four years later, Gavin is living a quiet life in a seaside village with a new woman and her son when the Iranians learn of his new identity as Frank Perry. The Iranians dispatch their arch assassin, the Anvil, to kill him. Intelligence sources discover the Anvil's intents and work to protect Gavin/Frank, but it may be a matter of too little firepower against a malevolent terrorist.
