The Meg (2018)

Five years ago, expert sea diver and Naval Captain Jonas Taylor encountered an unknown danger in the unexplored 
recesses of the Mariana Trench that forced him to abort his mission and abandon half his crew. Though the tragic 
incident earned him a dishonorable discharge, what ultimately cost him his career, his marriage and any semblance 
of honor was his unsupported and incredulous claims of what caused it - an attack on his vessel by a mammoth, 
70-foot sea creature, believed to be extinct for more than a million years.
