As Hiro and the others seize upon offers to join rival company Pinehearst Industries, Peter is changed for ever by a meeting with its shocking founder, as the cult US science-fiction series about ordinary people with superhuman abilities continues.

Impressed by his sudden ruthlessness, villains Knox and Daphne bring Hiro, among others, into the Pinehearst fold, and give him an assignment. With Angela and the Company paralysed by recent events, Peter goes directly to Pinehearst for answers, and is irrevocably changed by the shocking meeting.

Meanwhile, Claire and her mother, Sandra, attempt to free Meredith from the thrall of escaped villain Doyle, who has the ability to take mental and physical control of others. Later, Nathan brings Tracy to Suresh, hoping he can shed light on the surprising origin of their abilities.
