When action superstar Rob Riggle seeks to reinvent himself by starting a "personal watercraft education" academy, he struggles with the fallout from his first big scandal. Also there's a ghost.

To help with the Academy's growing money problems, Riggle welcomes a popular bass fishing show to shoot at the lake, but its down-home host is not what he seems. Also there's a mermaid.

During lake training, the cadets discover a vortex that vanishes anything that's thrown into it, which is a problem for the mandatory Academy inspection, but possibly the solution too? Also there's a sex robot.
