Rabid (2019)

After a young fashion designer, Rose, suffers a disfiguring accident, she undergoes an experimental stem cell skin and tissue graft treatment performed by Dr. William Burroughs.

Rose ends up attacking several people, as a parasite emerges from her face leading to a form of rabies where minutes to hours later her victims transform. Meanwhile, the fashion designer Gunter decides Chelsea, Rose's best friend and a fashion model, will launch Rose's first exhibition. Brad, a fashion photographer who formerly dated Rose, reenters her life.

After the epidemic spreads and Chelsea kills Gunter and is shot by police, Brad and Rose go to Dr. Burroughs to check on anomalies in her skin graft. Once there Burroughs traps both in a room and he reveals he told Brad about her parasite, and Burroughs's wife—who was his first subject—is revealed to be supplying the supposed stem cell tissue. She had cancer years before and ultimately died leaving a mindless immobile shell of tissue behind.

Brad is attacked by Burroughs's wife and the parasite inside Rose, which Burroughs believes will unlock immortality in humans. Rose uses Brad's knife to cut her parasite proboscis off and both her and Brad appear to die, but when Rose recovers, Burroughs announces plans to keep Rose captive for research, having cured the rabies pandemic.
