Hazel and Marc were paired together on “Love Synced,” a revolutionary reality AI dating show that matches hopeful lovers. But when it came time to say “I do,” Hazel left her perfect match at the altar. Now all she wants to do is fly home. Instead, she’s trapped at a tiny, snowed-in airport with her ex and his obnoxiously rich family. But when they start turning up dead, a jilted lover is the least of Hazel's worries. There’s a serial killer to catch first. The heart is a fickle thing, so it’s no surprise that AI couldn’t predict true love for Hazel. But can it help crack the case when a murderer is picking off her almost-in-laws one by one?

Kirby Cornell needs a break from everything: Her crumbling apartment in the sleepy town of Crowhurst (famous for its bucolic countryside and a second-rate serial killer from the ’90s). Her dead-end job. Her sleazy landlord. Her messy roommates. And, most of all, the terrible thing they all did. Luckily, that hasn’t caught up with her just yet. Until a new message on their old group chat pops up: Everyone in the group chat dies. It’s the first text that her ex-roommate, Esme, has sent in ages, but that’s not the really weird thing. The really weird thing is that Esme died 12 months ago.
