Deep in the swamps of Svartalfheim stands the Black Bifrost, Malekith´s corrupted Rainbow Bridge and the only reliable means of travel between the realms with the true Bifrost in pieces. If the gods are going to stop Malekith´s invasion, the Black Bridge must fall. With her son missing and husband injured, Lady Freyja must take up the challenge herself. But she won´t go alone. Hulk (Jen Walters), the Punisher, Blade and Ghost Rider follow the All-Mother of Asgard straight into Malekith´s home territory! While two other Strikeforce teams head out to other realms, Captain Marvel leads the fight to reclaim the Earth! Taking up Thor´s ax, Jarnbjorn, Captain America and his team - Spider-Man, Wolverine, Luke Cage and Iron Fist - invade the Frost Giant realm in search of their fellow Avenger.
