The first glaring plot hole would have been the same old tired excuse for cheating on her husband. Now if she had of kept to the abusive husband as a reason to move on, I would have bought that one. But he was all up into his job as a DEA agent, was weaker than two percent milk.
The second plot hole would have been the side piece seemed like a step down and not up, so I didn't buy that either, also I would have been inclined to agree with the abusive husband when it comes to the side piece also using her for sex, because he had little to offer.
Now the whole ruse with the kidnapping and torture, I saw through that and why would he "the husband" keep the side piece cellphone??? He's a cop, so why keep incriminating evidence is a major plot hole.
So I will give this a very generous three out of ten for the effort, but what happened to the black and white that was ordered to watch the suspects house?? Oh and yes it was predictable.
