This is the incredible moment inmates at a Texas courthouse broke out of their cell to save the life of a prison guard who was having a heart attack.
For the first time since the incident in 2016, guard Gary Grimm has spoken out about the experience, saying that he would not have survived if the group hadn't escaped from their cell and called for assistance.
In the footage, the inmates can be seen pouring out of their holding cell and checking on the guard. Several inmates disappear around the corner before coming back into shot with two more law enforcement officials.
The prisoners are then locked back up in the cell before the two men call for help.
Mr Grimm had been guarding the cells when inmates noticed him slump down in his seat and saw that he was unconscious.
"I just slumped and went out," he said. "Next thing I remember is looking up at the ceiling in the ER."
Now the Texan prison guard has voiced his gratitude to the men who put their differences to one side in order to save his life.
The 52-year-old told WFAA: "Instead of overtaking me and taking my gun, and killing me or taking a hostage and escaping, they looked at me as a human being.
"I get emotional. If they wished harm for me, all they had to do was sit there and do nothing."
The 52-year-old, who is now retired from his job, is set for open heart surgery this week to get a Left Ventricle Assistance Device (or LVAD,) installed.
"I need that for at least six months, and then maybe we can have a transplant," said Grimm.
Gary's friends have started a GoFund Me page to help the family with extra expenses as he awaits his operation, with the tagline 'a heart for man that has given his'.
