The objective of the mission is to meet with blackmailers of Bernie. Bernie explains that the people that he and Niko are meeting are representatives of the blackmailers in Northwood. He says to take a "fast and intimidating car", there is usually a Comet or Turismo nearby. Bernie lets the reps know that he will not negotiate with them, and it is revealed that they are representing Dimitri Rascalov. The player is instructed to chase and kill them, but it is easier to focus on the road, and eventually they will reach a dead end in Castle Garden City. The player can then exit the vehicle and kill Dimitri's men with a weapon.
- The name of the mission is double entendre referring to two seemingly unrelated topics. On one hand, the name references the nature of the mission: To drive in order to secure a "union" between lovers; on the other, it also references the names of highways where much of the car chase in the mission occurs, Union Drive East and Union Drive West.
- The mission is one of only a handful of occasions in the game when a Super GT is available to be taken.
