Seven Mile Road is an area in Detroit, Michigan, which is 'one of the most dangerous no-go zones in the USA', according to documentary No-Go Zones: World's Toughest Places.
While the city was once the heartland of the US automobile industry, it now faces huge issues with poverty and crime.
Nowhere is this truer, however, than in Seven Mile Road, which stretches from one end of the city to the other, and is home to 'drug dealers, hustlers, killers and thieves, prepared to do whatever it takes to defend their territory'.
A narrator says in the doc: "Those who live or dare to come here are playing with their lives. [...] From Detroit's no-go zone, death is the main escape route."
He adds: "Even the police only dare tread dirt in the day. The violent crime rate is five times higher than the rest of the country."
The west end of the area is ruled by the Seven Mile Bloods, one of Detroit's most notorious gangs.
Speaking in the film from behind a mask, the gang's leader 'Money' explained why he joined, saying: "It was more of a family thing, I come from a long line of Bloods."
Their main source of income is through dealing crack cocaine, with Money selling 1kg each month with a street value of $40,000.
"The drug game here is extremely dangerous," he says, adding: "Your best friend will kill you in this game."
Crack remains the most lucrative street drug in Detroit, where poverty and a 'lack of prospects' lead one in six people into drug addiction - with the Seven Mile Road market also flooded with other substances like heroin and opioids.
Money tends to send right-hand man Mo out to do his dirty work, who warns in the documentary of coming too close to enemy lines.
"If somebody from the rival side comes, there's automatic problems," Mo says.
"Either a fight could break out, a shooting could break out, stabbing - anything. But it's most definite, definite problems coming across the territorial line."
The area also remains a huge risk for police, which is why bounty hunters are often used to go after gang members.
In the documentary, we meet a special unit of bounty hunters, made up of former elite special forces, police officers and mercenaries.
Tommy Depung, who leads the unit and has so far arrested more than 2,500 criminals, says: "There's been a lot of drug-related, gang-related shootings, and so Detroit PD has been doing their best to be proactive with their gang units, but you can't get ahead of it fast enough."
