In the 12th CSI episode, entitled "Daddy's Little Girl," Warrick, Sara and Greg investigate the death of a young man whose girlfriend's relationships always seem to end in disaster.

When a young woman comes home after a night out partying, the last thing she expects to find is a dead body. Bianca has been out around town all night, doing everything from dancing, to drinking, to meth and ecstasy. It's four in the morning and Bianca should be beat, but instead she wakes her roommate, Chelsea, up, and the two decide to get some breakfast. Bianca suggests they take her boyfriend Ahren with them but Ahren has other plans - he's been dead in the garage all night.

Brass talks to Bianca, who is still grief stricken and drugged up – a bad combination. Bianca reveals she and Ahren had been dating for a few months, and were planning to move to Colorado shortly. This young girl can't help but remind Brass of his own daughter, and as Bianca begins to cry the detective can't say much to console her. According to Bianca, it seems all her boyfriends either leave or get killed. She thinks it's bad luck - the CSIs know better than to believe in such things.

In the bedroom, Greg and Sara find droplets of blood, and a quick search through CODIS reveals they belong to one Justin Roth. Brass interrogates Roth, who tells the detective he and Bianca used to have a romantic relationship just a few months prior to Ahren's death. Brass wonders if this is perhaps a crime of passion, but Justin claims he's moved on. Warrick is curious about the drops of blood in Bianca's bedroom – Justin explains he one day came home and an unseen assailant shot him in the leg, but not before asking him to stay away from Bianca. Seems whoever shot Justin killed Ahren as well, but was said person motivated by love or just jealousy?

Meanwhile, Nick and Catherine investigate the death of a woman who may have peripheral ties to one of the CSIs. When Sandra Mullins is found dead in the garage of the building where she worked, the CSIs investigate the case as if it were any other. Mullins was an accountant and she appears to have been run over with her own car. Whoever committed the crime didn't steal anything, meaning the killer was emotionally driven to kill Mullins. This run-of-the-mill case, however, becomes personal for Nick when he discovers Mullins had ties to Walter Gordon, who kidnapped and buried the CSI alive in the episode "Grave Danger."

Driven by the incessant need for answers, Nick is set to find the truth about Mullins, hoping the case will not only allow him to move on, but finally help him reveal who is the second voice on Walter Gordon's tape. The CSI is shocked to find out the evidence points to Kelly Gordon as Mullin's killer, but what motive could Kelly have had to kill Mullins? The CSIs are determined to find out, but their investigation may be fruitless - Kelly's parole officer, unaware of Kelly's involvement in the Mullins case, granted the young woman permission to leave Las Vegas. Now, the CSIs will have to find Kelly in order to answer some important questions: did she kill Mullins, and could Mullins be the key element missing from last May's ordeal? Nick must be able to tame his emotions in order to find out the truth.
