From the studio that inexplicably sewed his fucking mouth shut the first time, comes ... me! - Deadpool
Wade Winston Wilson, as seen in the trailer, is dying. He accepts to volenteer for a cure. The treatement, well "an unauthorised medical nuclear infused atomic experimental test", simply put injecting a fluid substance into the veins that tortures the patient physically and finally rips off his skin. But it gives the body an abilty to grow itself, again and again and once again.
Deadpool narrates his story, rather his first film. He had finally found a studio to finance his film (reality is that the Film got in and out of the cans for about 15 years and from New Line Cinema to Fox to Marvel dusted their hands on the franchise) and he is happy to walk us through the events that occured in his life in between a "car crashing gun blazzing" action sequence. Ofcoarse, he was Wade Winston Wilson, if you have not guessed it already, but now has become Deadpool the super-hero, oppps, the Super-Villain who has the revenge mode loaded up and errect to find the man who had done all this, well, who made him get behind a mask to hide his ugly face.
So, when Deadpool is kicking around, the villain kidnaps his girlfriend. Oh yeah, Wade Winston Wilson was in love with Venessa and Deadpool is in love with Venessa, still (oh! come on). Their first meeting was at a bar, where she had only 30 minutes of spare time. So they play with the games-machines, and when they find out that they only have 3 more minutes left, they perform a quickie. Throughly contended of sharing a same life style, the couple spend some fantastically gorgeous time with each other walked through by a Holiday themed sex routines.
"I ain't super, and I'm no hero. But when you find out your worst enemy is after your best girl, the time has come to be a fucking superhero." - Deadpool
Now Deadpool can't show his face to her, at the same time he cannot leave Venessa in the hands of Ajax whom he thinks had lifted his nick name for a dish-wash commercial. Here, Deapool turns quite serious, serious as exactly as in serious. He advices a cab driver - an Indian lost in Romance, gets along with friends and keeps his promises, gives the side-kicks a second chance and finally takes down Ajax keeping in mind what his friend Colossus had told him about being a super-hero - There are only four to fives instances in life that one gets to prove to be a real super-hero.
The film ends with Deadpool promising that he will make sure to look for the remaining 4 chances to become a Superhero.
... well, well, wait after the credit and don't tell anyone that I told you to !
