Teaser of Joss Whedon's new TV Show where the cast present their characters and Joss Whedon (Executive producer/Director/Writer) outlines the premise.

In the digital series premiere, a Double Agent infiltrates the set of Marvel’s Agents of S.H.I.E.L.D. Working for a shadowy figure known only as the Mastermind, he encounters series regular Ming-Na Wen (Agent May) and show co-creator Jed Whedon as he works to stay ahead of Marvel Security and uncover secrets of the show.

The Double Agent visits various production departments. He uses the opportunity to secretly gather intel for the Mastermind and in the process meets Adrianne Palicki (Agent Bobbi Morse), Costume Designer Ann Foley, and Prop Master Scott Bauer. But Marvel Security is always watching...

The Mastermind gives the Double Agent his most dangerous mission yet. After a run-in with Brett Dalton (Grant Ward), the set is put on lockdown by Marvel Security. While in the midst of a desperate cat and mouse chase, our Double Agent has an unexpected interaction with Elizabeth Henstridge (Agent Simmons).

The Double Agent is tasked with finding the Season 2 finale, but his mission does not go as planned. In the process of evading Marvel Security, he runs into Chloe Bennet (Agent Skye) and Post Producers Chris Cheramie and Robert Parigi.

On the run with a stolen copy of the Marvel’s Agents of S.H.I.E.L.D. finale, the Double Agent finds himself in a desperate car chase with Marvel Security. The Mastermind’s true identity is revealed and our adventure culminates in a startling conclusion. Special appearance by Clark Gregg (Director Coulson).

Elizabeth Henstridge (Agent Jemma Simmons) 受《结局的开始》一集的启发，对新兵的智力进行了测试。新兵必须在时间到期前快速求解一系列复杂的方程，才能救出被困在水下的菲兹。

新兵必须通过完成这项高空挑战来证明他们有足够的勇气作为宙斯盾局特工进行实地工作，这项挑战的灵感来自导演库尔森在《终结者》一集中的危险跳伞。Ming Na Wen（特工Melinda May饰）和Henry Simmons（特工Alphonso“Mack”Mackenzie饰）介绍了此次任务。布雷特·道尔顿（Hive饰）突然造访，并用一个狡猾的转折来增加赌注。

在这个模拟中，新兵扮演了一个新重生的异人，正在逃离九头蛇。新兵必须在比赛结束前通过障碍赛，并将坐标恢复到S.H.I.L.D.提取点。Luke Mitchell (Lincoln Campbell) 一路鼓励新兵，但布雷特·道尔顿（海夫饰）为挑战增加了一个高速转折。

学院新兵加入了克拉克·格雷格和漫威《神盾局特工》的演员和工作人员的行列，为他们在热播剧的一集中扮演特工做准备。在排练他们的场景之前，当新兵们仔细检查头发、化妆、服装和道具时，可以看看幕后的情况。
