Botany Breach

You’re a janitor on board a spaceship and have just woken up from your cryochamber???   The scientists on board are researching how various plants are affected by space.  However, a cosmic ray engulfs the spaceship, causing irregularities in some of the plants, allowing them to gain consciousness.  Several species of plants have gained the power to mimic the humans and blend in among them.  One thing is for sure, they don’t enjoy being experimented on.
