The first episode introduces five of the series' main characters. First introduced are Simmons and Grif as they ponder why they are in Blood Gulch, with a brief one-liner about Master Chief. The episode then cuts to Tucker and Church as they spy on Grif and Simmons and argue with each other over what the reds are doing. Back at the Red Base, Sarge interrupts the banter of Grif and Simmons and orders them down from the top of the base. (thetvdb.com)
