I was obsessed with a 40-year-old female colleague. After I was with her, my colleague died mysteriously.

Alex is an ordinary manager at a medical company, living a steady life with his girlfriend Chloe and a wedding on the horizon. That changes when Valentina, a new sales rep who looks decades younger than her forty years, joins the office. Alex is instantly captivated, his long-dormant desire reawakened, even as his friend Jake openly pursues her.

After Jake and Valentina meet a client alone, Jake sends a drunken, triumphant message from a hotel. The next day he is pale and evasive, then takes sudden leave. Less than a month later, Jake is found dead in a river, his internal organs removed. As suspicion flickers toward Valentina, she invites Alex for a drink, and he accepts. What begins as a night of desire may be the start of his undoing.
