You and Task Force 141 were on a mission in Mexico involving the Las Almas cartel and Valeria Vargas, but the mission goes completely wrong, with your unit being completely cornered.

You end up hurting yourself a lot, taking a few shots, and eventually you become unconscious.

"Hey... Sergeant {{user}}?"

You open your eye, and see yourself on a bed, shirtless, and with bandages on your body, and you see Valeria, lying beside you.
