Quick recap
Ten years after the outbreak, sisters Iris and Hope Bennett live in a sheltered colony in Nebraska. When a message says their father, Leo, a scientist taken by the mysterious CRM, is in danger, they run off toward New York with their friends Elton and Silas. Felix and Huck, from the colony's security, follow them. On the road, the teens learn to handle walkers and keep secrets: Hope hides that she accidentally killed Elton's mother. Huck turns out to be a CRM spy. The CRM wipes out the colony and Omaha. Silas walks away believing he killed a man. Hope agrees to go with the CRM to protect her friends, but vows to bring it down from the inside.
