Fast cars, motorcycles, and one-night stands have been Mac's life since she left the military. Bitter over a lost love and never one to gamble, she ends potential relationships with surgical precision to avoid another heartache. After her flight to Italy is delayed by a wicked storm, she intervenes when a drunk passenger threatens the desk agent. Impressed with her courage, fellow passenger Lana Baroni offers to buy her a drink. One coffee and an upgrade later, they spend the fight to Italy talking cars and racing. When a sightseeing date with Lana turns into an afternoon tryst, Mac has to choose: hit the brakes or roll the throttle and risk everything to win Lana's love.
