Ben is mourning the recent death of his sister, Karen, whom he believes to have been killed in a savage wolf attack. At her funeral, Ben is approached by the mysterious Stefan, who warns him that a cult of werewolves had attacked Karen and that she too will become an undead lycanthrope. Although dismissing his claim as mere superstition, Ben’s girlfriend Jenny convinces him that he should take Stefan’s warning more seriously, and, sure enough, Karen is soon back from the dead, covered in fur and complete with a deadly set of K9s. After being narrowly saved from a fatal bite by Stefan, Ben is persuaded that he’s telling the truth and volunteers to join him on his mission to destroy the increasing hoards of beastly creatures ravaging Europe. But as their journey takes them to Transylvania, where werewolves from around the world are gathering for their ritual, Ben and Stefan fear that they might be in over their heads, mainly once werewolf queen Stirba receives news of their arrival…

Australia’s king of B-movies, director Philippe Mora (Mad Dog Morgan, The Beast Within), delivers an outrageously blood-soaked sequel with HOWLING II: YOUR SISTER IS A WEREWOLF, assembling the talents of international sex symbol Sybil Danning (Reform School Girls), cult star Reb Brown (Yor: Hunter From the Future), musician and TV personality Jimmy Nail, alongside horror icons Ferdy Mayne (The Fearless Vampire Killers) and Christopher Lee (The Satanic Rites of Dracula). Loaded with memorably gruesome set pieces, delivered with tongue firmly in cheek, Vinegar Syndrome proudly presents the UHD debut of this beloved 80s horror classic in its uncut international form, newly restored in 4K from its original camera negative and bursting at the seams with new and archival bonus features.
