The Man (2005)

A federal agent turns up dead and a hardcore undercover agent, known as Derrick Vann heads off to try and recover the stolen arms and find the killers. Andy Fiddler is an ordinary family man and a dentist, and is out heading to a conference, when he gets stuck in the same mess. Criminal Kane believes Fiddler is 'The Man' behind it all and offers him a gun. Vann spots him and drags him across town, with him posing as the actual 'Man'.—simon
