GMAC is a former Lieutenant in the Vice branch of the Tri-City Bay Police Department. He justifies his retirement with the corruption of his employer and his need for illegal street racing. He is also the leader of a crew based in Sunset Hills.
GMAC first appears in the job - "Tri-City Tournament" - as the race organiser. He is described by the player's handler - Chase Linh - that he was "fired from the TCBPD for his brutal and sadistic tactics." GMAC gives the player a choice of pink slips to the other racers' cars.
The player soon starts working for GMAC. Their first job is to steal a Nissan GT-R R35 Super State Cruiser and then four Tier 1 cars in a "4 cars in 48 hours" story arc.
The player steals Chau Wu's Pagani Zonda F from a shipping container and frames Chau Wu for it under GMAC's instructions. The player also steals a Lamborghini Murciélago LP 640 that contains materials that could get GMAC 20 years in prison if the FBI finds out.
GMAC drives a white Lamborghini Gallardo LP 560-4 with black side stripes in the PC, PlayStation 3 and Xbox 360 releases of Need for Speed: Undercover. He drives a green Lamborghini Gallardo Coupé in the PlayStation 2 and Wii releases, and a blue Porsche 911 GT2 in the PSP release.
