To celebrate the release of Universal Playback’s “Heroes: Season 3” on DVD and Blu-ray from October 12, we are giving away two DVD box sets of the gripping third season.

With the Hollywood writers’ strike resolved, Season 3 explodes with “Villains” (originally destined for the second season). A new cadre of villains and fugitives, alongside a rejuvenated Sylar, appear to threaten the future of the Heroes, new and old alike. They are all battling for control of the “Catalyst” – a newly discovered formula that gives normal people similarly nature-defying powers.

Series debut “Villains” is a two-hour special with revelations that will redefine familiar characters and shake the series to its core. Months after explosions brought down Pinehurst and Primatech, our Heroes try to put the past behind them and begin new lives. Now powerless, Hiro tries to train a reluctant Ando to be a true superhero; Sylar begins the search for his real parents; Mohinder returns to life as a taxi driver; Peter is back saving lives, and Daphne and Matt are trying to become a normal couple.

But nothing is ever straight-forward for our superheroes and with a new volume come new dangers. There's a Hunter on the loose and Claire has just uncovered Nathan's deadly plot to track down and capture those with abilities.

Get re-acquainted with “Heroes”. All the time-bending action, the shocking twists, the mind-blowing special effects that made Season 1 Programme of the Year at the US Television Critics Association Awards and Best International Programme at the 2008 BAFTAs are working full-throttle in this series re-defining third season.
