On Christmas Eve, three thieves brutally murder a woman and one of her daughters, leaving behind a second half-dead daughter named Elena (Patricia Rivera). When Elena recovers, she decides to change her identity with plastic surgery and hunt down the killers, dispatching of them in gory ways that involve a chainsaw, a drill and much more. Only a cop (Roberto 'Flaco' Guzman) can stop her by following the bloody trail she leaves on her suicidal quest for revenge.
