>> After a jealous board member frames a high-flying CEO for embezzlement she hires a hit man to fake her own death to avoid jail but they end up working together to bring the jealous board member to justice.
I think this revised logline works rather well as a corporate sabotage story, but since the board member is mentioned first (the subject), it's unclear that the CEO is the one who hires the hitman and that she's the protag. Suggest reversing the order of the subjects in the opening phrase:
After a high-flying CEO is framed for embezzlement by a jealous board member, she hires a hitman to fake her own death to avoid jail and then joins forces with him to expose the board member's nefarious scheme.
Hope this helps
