In a desperate attempt to save his rapidly failing used car dealership, Ben Selleck hires a crack team of 'car mercenaries' to ramp up sales during the Fourth of July weekend. Led by the fast-talking, foul-mouthed, self-assured Don 'The Goods' Ready, the group has three days to sell over 200 cars. But as Don undertakes his newest mission, and quickly falls for the boss's daughter Ivy, he realizes he'll have to trust more than his cars and his crafty skills in deceit to make a success out of the daunting weekend.
