Remember that feeling when you saw the first Terminator movie? Or the stand-off between Uma Thurman and Daryl Hannah in Kill Bill? That maybe indicates just how far my jaw dropped watching Redux Redux at a festival screening.
Irene (Michaela McManus) and Mia (Stella Marcus) are such feisty characters they'd blow their own feet off rather than work as a team. Irene is a hardened fighter, killing on a regular basis to avenge a brutal kidnap, sickening torture and grisly murder of her daughter. Mia (also Irene's daughter's age) is on a risk-everything, nothing-to-lose learning curve that catapults her into combat or compact with the older woman.
The solidly used plot device that thrusts them together is the multiverse - parallel versions of reality with occasional differences - plus a heavy-metal, grungy-chic lump of hardware in Irene's pick-up truck to jump between parallels.
Revenge that will stop at nothing is complicated by the gruesome resourcefulness of psycho-kidnapper Neville and the pervy designs of some hardware maintenance techs. At what point can merciless revenge and self-preservation cave in to some sense of humanity?
The multiverse idea works as metaphor (as with all the best sci-fi). We all make life-decisions at points in the present, often based on how we 'perceive' reality. My takeaway from Redux Redux is this: Have you found a 'version' of 'reality' that works for you? If you have, stick with it. It might not come back. (And see Redux Redux in festivals or cinemas while you can!)
