Misha is an incredibly hard worker at "LocalMegaCorp" LLC, a totally legitimate business with nothing to hide.
Misha of course, is the hardest worker in the entire company - working days and nights, sometimes sleeplessly, in order to get all the work possible done. He even took extra work. Within days, he got several promotions
But Misha neglected to actually see anything but his work in of itself, and even though he saw some suspicious activity, he never thought by of it because there was always more work to be done.
What Misha had actually saw was a plan by "LocalMegaCorp" LLC in order to sabotage a local chemical plant, causing the local plant and wildlife to die for construction space.
Misha soon remembered the suspicious plans he had discovered earlier, however he was too deep into his work to have even thought of doing anything then. Surrounded by stacks of paper and in posession of the very plan that caused the area to essentially die - his great error had been realized.
Though after a swift plea to the government outside of the area, both LocalMegaCorp LLC and Misha were brought to justice. Of course, the corporation for killing everything - and Misha for staying compliant, even with knowledge of what was going to happen.
