Petty Officer Michael Davis (Jeremy Davis) is the newbie to SEAL Team VI, but after his first mission the young soldier is weathered beyond hid years. His first assignment as for the elite black ops squad is as Communications Officer for the micro ground assault team that enabled surgical aerial assaults of strategic targets in Iraq, priming allied forces for the what is now known as Operation Desert Storm. The honor of being part of the special forces unit is enriched by the fact that he is invited into the unit lead by the best, Master Chief Devon Mackefy (Ken Gamble). The team, having just returned from one mission, is called into duty once again, because “Mac is the best”. Feeling the pull of the call, and given no option by the powers that be, our heroes go into the thick of it with the usual disadvantages - tired, short by one man and in need of gearing up in the weapons department; all with their invisibility being paramount. The team is rounded out by Petty Officer Williams (Kristoffer Garrison), Petty Officer Sanchez (Neta De Paula) and Chief Petty Officer Roberts (Zach McGowan). The team’s only contact ii Iraqi is Jamal (Amol Shah), a Kurd who has lost his family to the war and now helps the U.S. in these isolated covert operations. Their sole mission: mark aerial targets, avoid capture and stay alive for four days. But the enemy is in every direction. Tensions are high since Davis is untested in the field and Mac is distracted by a recent personal loss. All these complications threaten the success of the mission, as well as the team’s survival.
