Mia first appears in one of the opening scenes driving a red Mazda RX-8 as the player follows her upon arriving in the city of Rockport. The player receives help from Mia after they lose their BMW M3 GTR to Razor.
She phone calls a person known as Al and takes the player to his car lot to buy a new car as well as provide a safe house located near Heritage Heights in Rosewood.
Mia will ask the player to turn a blind eye to any side bets that she places on them after beating Taz. Mia also gives the player access to the Rap Sheet and also provides many gameplay tutorials via SMS.
Mia reveals she is an undercover police officer with the Rockport Police Department after the player defeats Razor. She still assists the player out of the city to escape Cross, the Rockport Police Department and the city by releasing directions to an old drawbridge.
