"A Man Apart" begins with workers in Mexico processing cocaine for distribution in the United States. This gives way for the theme for the rest of the movie.

Meanwhile, DEA agents are setting up for a drug bust outside of a secret hideout of a group of Mexican drug leaders known as the Baja Cartel. Agent Sean Vetter, played by Vin Diesel, arrests the head of the Cartel, Men Lucero, played by Geno Silva, and he is sent to prison. Vetter and his partner, Demetrius Hicks, played by Larenz Tate, are part of the DEA’s narcotic squad, which is made up of former gang members who are trying to crack down on the drug war on the US/Mexican border.

Vetter and his wife, Stacy, played by Jacqueline Obradors, are madly in love. Soon after Lucero is imprisoned, there is an attack on the Vetter’s home by two Mexican men and Stacy is shot and killed. Vetter is now outraged, and finding out who killed his wife becomes a personal task he must complete.

Vetter visits Lucero in prison and asks him if he had his wife killed, but Lucero says no. Vetter does not believe him.

Now that Lucero is in prison, his drug empire is being wiped out and taken over by a mysterious character, named Diablo, who no one can identify. Vetter and Hicks begin setting up drug deals and posing as dealers in order to figure out who Diablo is. A few of the drug scandals go badly because Vetter begins taking the case personally and causes people harm because he is so enraged about his wife. DEA agents are killed, and Vetter’s boss puts him on suspension.

Lucero has Vetter meet him at the prison again, and Lucero tells Vetter that his own wife and son have been killed and he wants to help Vetter. In exchange for the information Lucero will give him, Vetter has to have him transferred to another prison because he claims he is not safe at the prison he is at now. Vetter arranges the transfer and calls some of his gangster friends from his street days to help him find Diablo.

During Lucero’s transfer, the vehicle is traveling in is hijacked by his cartel, and he is taken back to Mexico. When Vetter finds out about the escape, he realizes that he has been tricked. He goes to Mexico to inform Lucero that he knows that he created the name Diablo as a scheme and he helps the Mexican police capture him.

The movie ends with Vetter at the cemetery where his wife is buried, coming to terms with her death.

This movie has thrill and romance. It is a good movie for both romantics and people who like action-packed films.
