Deadhead.

Wendy is a middle-aged woman who is constantly dismissed and made to feel invisible by the men in her life. One day while working in her garden, she pricks her finger on a thorny cocoon, and is infected with something… inhuman. After she is suddenly let go and replaced with a younger woman by her boss at a job she’s enjoyed for decades, her rage, (along with alien DNA), transforms her into a powerful creature, hellbent on revenge.
