Trapped, terrified and cornered, Nathan, Tracy, Matt and Peter struggle for their lives against a much-changed, monstrous Suresh, and attempt to free themselves, Maya and the doctor’s other “test subjects”, as the cult US science-fiction series about ordinary people with superhuman abilities continues.

Elle returns with a shock for Claire and her family, while, aware of Peter’s ruthless take-down by her rivals at Pinehearst, Angela reaches out to convince Sylar to save his brother. Since Matt won’t sign up with the villains, Daphne is ordered by her boss to go back and kill him, or be killed herself.

Meanwhile, in awe of the African precog’s power, Hiro still questions Usutu’s advice on how to best face his gathering opponents.
