Nash and Joe are in hot 'Cuda pursuit of the Seau brothers, Larry and Manny. The two cars pull over and the two sides exchange heavy gunfire. Just as Nash and Joe are about to charge the two drug dealers, the gunfight is interrupted by soldiers with red berets. The soldiers are heavily armed with AR-15 rifles and chase the dealers away, leaving Nash with questions about their leader William Robard.
Robard is a decorated Gulf War veteran hired by the Hunter's Point area of San Francisco to provide private security in the crime ridden neighborhood. Nash spots a young boy in the area named Mike Gomez, son of Rosa Gomez. Rosa is ex-wife Lisa's employee in her catering business.
Joe has been on edge due to wife Inger's impending pregnancy. Inger keeps paging Joe with false alarms. Inger also pressures Joe to get back his great grandfather's treasured cradle for the expected newborn. Joe has lent the cradle to Nash seventeen years ago, but Nash and Lisa don't recall where the cradle is.
While searching for the cradle, Nash finds an undelivered letter from ex-wife Lisa addressed to him, dated just prior to their divorce.
Nash suspects that Robard and his men are ripping off and killing the drug dealers in Hunter's Point, with seven dead so far. Nash and the SIU search Robard's headquarters looking for the AR-15 rifle used to kill the dealers, but with no success. Nash convinces Mike Gomez to quit dealing drugs, so Mike tells Nash and Joe where the Seau brothers are hiding. But Robard and his men get there first and kill the brothers and steal their money and drugs.
Nash learns from Mike that Robard and his men are also looking for Tyrell Owens, another dealer about to move $300,000 of cash and goods. Robard attempts to shut up Mike by showing up at his mother's house. Nash intercedes to save Mike, but not before Mike is shot in the leg by Robard.
Lisa recalls that Joe's cradle has been given away to a retirement home of Nick's. Nick locates the home and gets the name of the person the cradle was sold to. Joe visits Suzy Depree to buy back the cradle for the $75 she paid for it, but Suzy jacks up the price to $400, forcing Joe to pay.
Nash and Joe go to Tyrell Owen's hide-out, only to find Tyrell dead. Robard and his men are already there, and they take Nash and Joe captive. At the worst moment, Joe's beeper goes off - a message from Inger that she is having the baby. Nash and Joe escape by throwing a spare ammo clip into the fire. Robard trips and drops his pistol, forcing a showdown with Nash. Nash shoots Robard dead.
Nash gives Joe the keys to the 'Cuda to rush to the hospital to be there for the birth of his child. But the doctor has decided to switch hospitals at the last moment, so Joe arrives at the wrong hospital, in the wrong delivery room. After Joe gets to the right hospital, Inger is waiting, along with Nash and family with the newly arrived baby girl. Nash decides to renew his relationship with Lisa after they discuss her letter in which she declares her love for Nash, even after the divorce.
