Scared Shitless plot
Plumber Don takes pride in his work. His son Sonny is a bacterophobe with an easily upset stomach. Sonny's mother recently passed away from a bacteria-related problem, which puts Sonny even more on edge. When Don gets a call about a plumbing problem, he decides to bring Sonny along to hopefully get his son out of this mentality. The job turns into a nightmare when they come into contact with a slug-like creature that is out for blood in an apartment toilet.
