Petro Vlacic was a foreman at a port in Odessa. He was also the husband of Maria Vlacic and the father of their son, Eugen.

Underground
Petro is first seen at work with Jack Bauer, complaining about how his mother wants more grandchildren. After they depart, he's confronted by Alik and Sasho, who inform him that his brother is in debt to them, and now he has to pay. When Petro refuses to pay, the enforcers tell him that instead of paying with money, he has to steal a container filled with methylamine, or else they'll threaten his wife and son next. Petro later tells Jack about his dilemma, and he agrees to help Petro out, so long as Sofiya doesn't find out. Petro and Jack succeed in stealing the shipment from the container truck and deliver the drugs to the gangsters. Before they can leave, Mishka Grenkov, the leader of the gang, recognizes Jack as the man who killed his father and brother. Grenkov's men take Bauer and Petro hostage moments later.



Much to Petro's surprise, he finds out that Bauer (who has been living under the pseudoname Borys) was lying about his identity. Before he can find out the truth, Jack assault Grenkov, and the two flee his compound. While driving away, Petro questions Jack about who he is, concerned about his sister's safety. Jack tells him Grenkov is merely playing with his head, moments before they're run off the road by Artur and another one of Mishka's gangsters. Jack kills the assailants and the two escape their burning vehicle; Petro starts to panic when he realizes his family is in danger, and he and Jack hurry home to save Petro's family.

Petro returns home and tells his wife that she needs to get Eugen so they can hurry and leave, but Maria refuses to go, curious as to why both Petro and Jack have been wounded. Before they can leave, Jack discovers Sasho and two thugs outside of Petro's apartment complex. Jack kills the three men, and he, along with Petro and his family escape. Petro urges Jack to go to the police, but Jack tells him they need to rescue Sofiya first, who is also in danger.



Petro and Jack arrive at Sofiya's apartment too late; Sofiya has already been abducted by Mishka's gang. Petro blames Jack for Sofiya's predicament, but he reassures him that nothing will happen to her. He takes Petro's family to one of his safehouses, where Petro begs Jack to call the police again, but he refuses. Jack later tells Petro that Mishka called him, wanting to trade his life for Sofiya's. He tells Petro to come along with him in case something happens to him, since Petro will be able to rescue Sofiya is Jack dies. Maria begs Petro to stay behind, but he tells her that he needs to go so he can rescue his sister. Petro also finds out that Jack was really part of the CIA when he discovers a cache of weapons. Jack hands Petro a gun as a precaution, and the two men leave.



Mishka calls Bauer again and tells him to meet him beside a billboard alone. Bauer pulls over and tells Petro the situation; Petro offers to hide in the back of the truck, but Jack tells him he has a different idea. While Jack stays in the truck, Petro follows him and Alik to the meeting place. However, shortly after Jack parks his car, Grenkov's thugs find his car. One of the thugs points a gun at Petro; Petro pleads for his life, but the thug guns down Petro before he has time to reach for his gun.
