This is a smart and nifty two hander that gets increasingly claustrophobic as the plot unfolds.
This is exactly similar to another British film the name I don't recall which has Olga Kurulenko in a similar plot.
Anyway turns out that one of the criminals is known to the victim. Once the breach occurs in the plot, it starts unraveling for the kidnappers. It's a slow burn that doesn't transgress it's plot moorings. Will worth your time.
