Samantha left her "chemist kit" in a "legit" location in the middle of nowhere? Can you be a dear and bring it back to the city for her?
The Smuggling Mission can be started from the brown flag icon at Cypress Flats/Popular St as a civilian. Enter the checkpoint to start the mission. You will have 12 minutes to complete the mission.
Drive in any vehicle to pickup the goods in the country. Follow the yellow line marked on your mini-map to the yellow briefcase. Drive into the red checkpoint to pickup the goods.
After picking up the goods, the delivery location will be shown on the map. Drive as quick as you can to the delivery location. Make sure you are not spotted by law enforcement agents.
Once you deliver the goods, you will receive a reward and certain bonuses.
Type /cancel at any time during the mission to cancel it.
