Coral Bowe isn't your typical assassin. She's the only one in the world with the power to steal souls from the young which she sells to elderly elites so they can extend their lives and absorb the talents of the targets. She's cornered the market for years.
But after so long servicing the sick whims of the wealthy, Coral is done. One last big hit and she's over and out and able to retire with her son 10-year-old Marlon and blend into normality on an island community somewhere warm and exotic.
With a new target acquired and a hefty price tag agreed with her broker, Henry, she embarks on her final 'soul tapping' mission. But there's a snag. The target is not alone and heads home for an evening of romance with someone they picked up in a bar.
Later, in the darkness of the target's apartment, Coral unfurls from the shadows, eliminates the love interest and settles in to execute her primary objective.
After performing the soul tapping ritual, where she physically sucks the life out of her targets with the deadliest of kisses, something goes horribly wrong. Coral isn't the only one in the apartment with murder in mind.
