The stakes are higher than ever when, after blowing their cover and damaging the Zephyr in the process, the team must scramble to rescue Mack’s parents, save S.H.I.E.L.D. from a chronicom infestation, and fix the ship ... all before the next time-jump. Meanwhile, Daisy and Sousa find themselves at a disadvantage against a power hungry Nathaniel Malick and his goons, and Coulson will have to do the thing he does best in order to save the future.

Emori tries to heal Sanctum's old familial wounds while Echo, Octavia and Diyoza struggle with new ones.

(God is within her, she will not fall; God will help her at break of day.) Confused but excited by her newfound abilities, Ava soon realizes she's in over her head, but her need for a helping hand may be a blessing in disguise.

(She is clothed with strength and dignity, and she laughs without fear of the future.) After tasting the good life with JC, Ava crashes a swanky tech party with his friends. Mary goes gunning for the people behind the attack on her sisters.

(Put on the full armour of God, so that you can take your stand against the devil’s schemes.) Ava takes her first steps towards understanding the halo's power, but a baptism by fire at the hands of the Order leaves her feeling burned.

(The whoredom of a woman may be known in her haughty looks and eyelids. If thy daughter be shameless, keep her in straitly, lest she abuse herself through overmuch liberty.) As Ava contemplates starting over, she recalls being left to the tender mercies of the orphanage. The Sister Warriors suit up for a dangerous mission.

(Enter through the narrow gate. For wide is the gate and broad is the road that leads to destruction, and many enter through it.) While Mary squares off with Sister Lilith, Ava begins to open up to JC, and Jillian Salvius fires a warning shot at the Church.

(Although the Lord gives you the bread of adversity and the water of affliction, your teachers will be hidden no more; with your own eyes you will see them. Whether you turn to the right or to the left, your ears will hear a voice behind you, saying, "This is the way; walk in it.") Ava experiences a come-to-Jesus moment courtesy of Mary, who pulls no punches as she shows her just how many souls have their own cross to bear.

(You were taught, with regard to your former way of life, to put off your old self, which is being corrupted by its deceitful desires; to be made new in the attitude of your minds; and to put on the new self, created to be like God in true righteousness and holiness.) Hoping to find some answers, Ava puts her faith in science. Meanwhile, Cardinal Duretti's machinations sow seeds of dissension inside the Order.

(The wise woman builds her house, but with her own hands the foolish one tears hers down.) Secrets are revealed and a Sister Warrior mysteriously returns to the fold as Ava and her allies attempt to keep a sacred object out of the wrong hands.

(The weapons we fight with are not the weapons of the world. On the contrary, they have divine power to demolish strongholds.) Infiltrating the Vatican to find a tomb hidden deep underground for a millennium? Hell, Ava may need a miracle to pull off this mission.

(Do not be afraid of what you are about to suffer. I tell you, the devil will put some of you in prison to test you, and you will suffer persecution for ten days. Be faithful, even to the point of death, and I will give you life as your victor’s crown.) In shock over the contests of the tomb, Ava no longer knows what – or who – to believe as she tries to divine the true history of the halo.
