Info
It's 3 minutes for hearers, but a life for the callers. A crime thriller chasing even the slightest sounds to rescue people's lives calling for urgent help.
Ella-May O'Brien
Each character in this movie — down to the smallest one — is an individual rather than a type, prone to spontaneous changes of mood and sometimes amusing outbursts of pettiness or ill humor.
Justina
The film never slows down or bores, plunging from one harrowing sequence to the next.
