Během minulého století zmizelo z povrchu planety beze stopy nejméně čtyři tisíce čtyři sta lidí, kteří byli přehlíženi, podceňováni nebo jinak marginalizováni. Včera v noci se nevysvětlitelným způsobem všichni v mžiku vrátili do Detroitu, aniž by zestárli o jediný den a aniž by si pamatovali, co se jim stalo.

4400 je ještě více rozčarováno ze svého ubytování a nová pravidla všechny znervózňují. Andre a LaDonna pomáhají Claudette posunout její nově nabyté schopnosti na novou úroveň. Shanice dostane nečekanou návštěvu.

LaDonna se přihlásí na dalších 15 minut slávy, ale rychle si uvědomí, že už nemá takový vliv jako dřív. Jharrell si vybere nevhodnou chvíli, aby řekl svou pravdu, a to ho může přijít draho. Andre se touží vrátit k medicíně.

Finally there is some good news for a few of the 4400. Andre looks to study some of his new friends but mistakes from his past begin to affect him in present day. Rev finds some information about his son.

Keisha hears the truth about the day she lost her sister, moving her to take a chance. Shanice and Andre enjoy a day out. Hayden and Mariah grow closer.

Jharrel and Keisha must earn the trust of the 4400 if they want to help keep them safe. Hayden convinces LaDonna and Andre to visit Ypsi Med and Rev continues to grow his flock.

Claudette begins to assert her independence. Rev keeps his flock close, further raising Jharrel's suspicions. LaDonna considers her next move. Keisha has a date with Jessica. Andre is concerned by his latest discovery.

Logan's adjustment to Shanice's return has been harder than he let on, meanwhile, Rev is beginning to see the light. Mildred lets her emotions get the better of her, possibly endangering the rest of the 4400.

The scene is chaotic, and everyone is still reeling after Mildred's on camera performance, meanwhile the government tries to figure out their next move. Rev is confused by his new ability, Jharrel get some unexpected news, and no one seems to know Ladonna's whereabouts.

While Shanice helps to prepare the Bois Blanc for a celebration, others are preparing for war. LaDonna returns to the hotel and we learn what she has experienced out in the real world and what she knows about the 44orum. After a disturbing incident, Hayden realizes the comfort of Kaminsky home may not be what is safest for everyone. Jharrell reunites with his brother but is Manny to be trusted and what is his connection to Claudette? Meanwhile, an unfortunate misunderstanding might prove fatal for one of the 4400.

Logan is the only witness to a savage crime, that, to all others does not seem to exist, meanwhile Claudette stands up to a group of anti-4400's. Mildred rallies the troops when she fears Milicent might be in trouble and we get a glimpse into the sisters' lives growing up and the mysterious Caleb.

Tensions rise as an attack is made on the Bois Blanc, putting everyone’s life in danger. Shanice and Logan do their best to keep Hayden safe, while Claudette and Jharrell try to reason with Manny. Meanwhile, Mildred still believes her sister can be saved and LaDonna takes to the streets in an effort to end the threat against the 4400.
