A pair of drug dealers were ambushed and stabbed to death by a pack of young men in a "swift, frenzied, utterly brutal attack" in a quiet residential street, a court heard.
Aaron Carriere, 21, and Josiah Manful, 20, were "lured" to a road in Leytonstone, east London, where they were "boxed in" by their killers and stabbed 24 times in under a minute.
Five young men and two youths are on trial at the Old Bailey accused of the double murder in the early hours of Saturday March 1 this year.
Prosecutor Lisa Wilding QC said the two victims were set upon in their black Ford Fiesta in Montague Road having been trapped by four cars which stopped in front and behind so they had no means of escape.
She said: "The occupants of the four cars that boxed in that lone vehicle got out and ran to the trapped car. Inside it were two young men - Josiah Manful and Aaron Carriere.
"Less than a minute later those two men were fatally wounded having been stabbed in a swift, frenzied, utterly brutal attack that left Mr Manful with 13 wounds and Mr Carriere with 11."
Mr Manful managed to get out of the driver's seat to call for help but both men were mortally wounded and were pronounced dead at the scene.
Jurors were told that the defendants had been "working as a team" to "lure" the two young men into a trap and kill them.
Although there were drugs and cash in the car, only one item was stolen - Mr Carriere's mobile phone which contained his drug dealing "client list".
The prosecutor asserted: "The ferocity of the attack, which was inflicted upon men who were helpless and trapped in their car seats, by a pack of men who surrounded the car, the use of at least two knives, the stab wounds to the neck and torso that killed them, were all intended to cause at least very serious harm and we say was intended to kill them."
Each of the defendants played their part in the murders, some wielding knives, some lending support through physical intimidating presence, and others acting as getaway drivers, the court heard.
Afterwards, some of the defendants tried to evade capture by dumping cars and fleeing the country in the days after the attack, the court heard.
Mr Carriere was a "successful drugs dealer" selling crack cocaine, heroin and cannabis on the streets of Leytonstone and, unbeknown to him, was the subject of an undercover police probe.
On the night he died, he had been dealing drugs and may have been planning to sell more because he had four packages of crack and eight of heroin rolled together and hidden in his pants as well as £700 cash in his man bag.
Mr Manful had apparently worried for his safety because at the time of his death he had a lock knife hidden in his boxer shorts, the jury was told.
Devonte Campbell, 20, Casey Jones, 19, Alex Bernard, 21, Omar Hassan, 21, Wail Alawi, 23, and two 17-year-olds who cannot be named for legal reasons, all from east London, deny two counts of murder.
