Ryan Reynolds plays a truck driver in Iraq who’s kidnapped and wakes up inside a coffin.

Playing on your worst nightmare, this heart-stopping, chilling thriller never loses its grip from its opening scene to its brilliant closing moment.

The film, shot in just 17 days, focuses entirely on Reynolds and his desperate predicament as he  uses the only things at his disposal, a lighter and a mobile phone, to try to get help before his air runs out.

It’s compelling, clever film-making by director Rodrigo Cortés and Reynolds’ tour de force does it full justice.
