Jessica Fletcher takes up the cause of her good friend Barbara "Babs" Wirth after Babs' husband Hal suffers a fatal heart attack that Jessica has reason to believe was actually murder. At the heart of her suspicions lies a sinister dating site Hal had used while he and Babs were having marital issues—a site that may be complicit in somehow swindling him out of millions. Jessica's investigation reveals that Hal was far from the only victim and when his former business partner is also killed, a deadly pattern emerges. Jessica teams up with a brilliant young computer hacker to follow the trail but as she gets closer to the truth, two near misses force her to realize that she may very well be the next victim. The stakes have never been this high as Jessica finds herself being stalked by the killer she is trying to catch. She must now set the perfect trap to avoid her very own date with murder.
