Orcs travel from their dying world to Azaroth. They are using a mystical power source called the Fell that feeds on living things. They need to gather many humans, demi-humans, etc on the Azaroth side to bring over the rest of their population.
The Human kingdon at Stormwind is opposing the Orcs and receive no support from the other races of Azaroth. The Humans seek the aid of their Guardian (think Gandolf) of Azaroth. The Humans end up capturing a Half-Orc for information on their new enemy.
The Humans wage an attack with their remaining forces to stop the Orcs from opening a gate to their homeworld and prevent the rest of the Orcs from coming through.
TL;DR Meh. All over the place plot. Pure setup for a franchise without good storytelling. Save your money and wait for it to hit Netflix or SyFy.
