Heroes is an action-packed US drama following the lives of ordinary people who discover they have extraordinary abilities. Season Four: Volume 5 'Redemption' begins as the dust settles from last season, and our heroes attempt to go back to their ordinary lives. But, as they will quickly discover, it's not easy to go home again.

As they attempt to readjust they will meet a strange and dangerous carnival comprised of a travelling band of outsiders with powerful abilities, led by a charismatic and powerful leader, Samuel. Alongside Samuel is his right hand man, Edgar, a deadly Speedster with a talent for knives, and Lydia the Tattooed Lady.

Samuel leads his flock to intersect with the lives of all of our heroes. He will find them, and he will entice them to join him. And together, they will ask the same basic questions: Who are we? What does having powers mean to the world? How should we live our lives - shameful or proud? Should we hide or live out in the open? And if the world of powers is revealed, how will the world ever recover?
