A beast gets loose in a laboratory, killing all in it's way. A former scientist, now working as a custodian tries to stop it.

Why it matters

A gritty, eighties creature feature that mines body horror and bio-experimentation fears with grimy practical effects and relentless tension.

  • Embodies late-’80s low-budget sci-fi horror, mixing lab-set paranoia with slasher-style kills.
  • Practical creature effects carry the film, leaning into grotesque mutations that recall Bottin’s work without the budget.
  • Centers on a flawed, down-and-out protagonist—a custodian ex-scientist—offering an underdog angle rare for the era’s monster movies.
  • For fans of bio-horror and experimental creature flicks who don’t mind rough edges in exchange for atmosphere and practical gore.
