Adoring Zoe

Thanks to his informant, Greg has learned of a group of Russian mafia is setting up shop in Las Vegas. His new mission is to be recruited into them and take down the mob from the inside.
The moment he meets Zoe he thinks he can use her as a tool to take down the boss, but the more time he spends with her, the more he realizes things aren't as they appear about Zoe.
Zoe is working undercover for the FBI and has been assigned to get close to the mob boss and shut down his operation. She is intrigued by Greg from the beginning but she knows he's hiding something from her and she is determined to find out what it is before he blows her mission.
When it is discovered they both have the same goals, Greg suggests they work together to take down a common enemy, but Zoe has been undercover for so long that she no longer recognizes friend from foe. Even one offering to help her complete her job.
Can Zoe learn to trust him and work together to take down the crime boss together? Or will her distrust blow the mission?
