When Charlie Mack is hired by her ex-husband’s new wife, things get awkward quickly. Her ex, Franklin, has been charged with his brother-in-law’s murder. Charlie and Pamela both believe he didn’t do it; it’s the only thing they will ever see eye-to-eye on. But he’s also in hiding for some reason neither of them understands. To the police, it adds up to guilt, but to Charlie, it indicates that Franklin has stumbled into an unplanned, and perhaps life-threatening, complication. Charlie wants proof the case doesn’t involve a double cross, and when the Mack Investigations team throws all their assets at the case, Charlie's girlfriend, Mandy demands assurance that Charlie’s all-out efforts to find Franklin aren’t driven by lingering romantic feelings. In the end, everyone involved learns that loyalty often runs much deeper than love.
