Three Split Seconds takes place on the beautiful Maine coast, in the small town of Camden, where Macie Black has decided there must be more to life than a marriage in which her husband doesn't come home at night. After hiring a private investigator to get her the proof she needs, she races toward what she's sure must be greener grass. When circumstances cause her plans to come to a screeching halt, she wonders if she should have left well enough alone. As the water grows murkier around her, she must decide to dive deep into this new reality or jump ship altogether. Knowing full well how much one choice can impact the next, Macie clings to the hope of sweet vengeance, unsure of what that would even look like but desperately searching for it anyway. Nothing can hinder her path to a brighter future. Not a dead body, or a mistress, or a father-in-law with a vendetta; she must go on.
