Michael, Trevor, Franklin and Lester are at the Vanilla Unicorn to plan the upcoming Union Depository heist, how they are going to go about it and which crew they are going to use.
There are two options on how to go about this mission, the Subtle or Obvious approach.
Michael and Trevor take the two secure cars that are on their way to the Union Depository. Getting in without alerting anybody and transporting the gold away in different vehicles, three modified gauntlets. The transport grid will also have to be manipulated to ensure they can get out of the city.
Franklin uses a drill to get into the vault to take the gold directly from it. Michael acts as a distraction at the front of the bank. Trevor airlifts the gold from the new Metro tunnel and takes the gold to the train.
