When parents “Maddie” (Rosamund Pike) and husband “Frank” (Matthew Rhys) get a call from their teenage daughter to say she has been in a road accident, they immediately get into their car and head to the quite far distant and remote scene. The rest of the film sees the couple trying to think what is best to do as the paramedic mother tries to help with an immediate problem whilst the father takes a more long-term and sacrificial view in the event of a worst case scenario. Things only get more fraught when another couple encounter “Alice” first and her folks become increasingly concerned that their “help” might only make matters even worse! With only the intensity of their car as the scenario as this all takes place via the telephone, and what I must admit was probably the slowest and/or safest driving to the site of an accident I’ve ever witnessed on film (or anywhere else, for that matter) we are introduced to a couple with demons galore and a somewhat confused sense of the ridiculous and of their own priorities. It’s that very superficiality and flakiness that makes this a bit more potent than your average thriller and at times it has a characterful intensity akin to a late night radio play with limited visuals and audio: just two people and an increasingly effective and frenzied script. Rhys tends to overact a bit but Pike and the gripping pace of the film deliver something that asks what we might do for our kids, but in a much less typical and frankly more pragmatic fashion. It’s only eighty minutes long and that really helps to keep the film focussed and though it isn’t a film you are likely to recall for very long, it does work well enough on a big screen.
