40 years after a meteor crashed in to the planet, army scientists try to remove a highly volatile substance but discover that trying to fly it out doesn't work as the speed causes it to become unstable. A retired expert is called out to advise on what to do with his advice being to use the largest ship possible to take it out to the deepest part of the ocean and drop it in order to prevent Armageddon. But things don't go smoothly with a rogue wave causing containment issues as time runs down.
I honestly don't know if that synopsis actually covers what goes on in "Super Tanker" or not because this is one movie which is all over the place right from the word go with an opening scene which sees some kind of meteor crashing in to the planet before jumping forward 40 years and the unexplained attempt to move something very dangerous. Unexplained is the key here because we never get explanations to what is going on and why. All we get is a group of people shipping this unstable item and a series of calamites making things messy.
Now if we had been presented with some decent characters, decent action and decent special effects then maybe it would work despite the inconsistent story. But nope we get none of that stuff either as it is all weak and as inconsistent as the story as is the acting. In the end let me put this plain and simple, about the only thing you might remember about watching "Super Tanker" other than how bad it is, is that Jon Mack who plays Morgan is eye grabbing.
What this all boils down to is that "Super Tanker" is not only a bad movie it is a stinker of a movie and has no redeeming qualities what so ever.
