The Million Dollar Tip (2014)

A randomly selected (as far as we know) server in a popular restaurant is given an envelope by a mysterious man in fashionable attire. Contained in the envelope is a check for one million dollars. There is no explanation as to why the envelope has this much money in it, but has been rumored to be addressed in a possible sequel. The server goes right to a casino and makes turns the one into four million dollars, but is pursued by the owner of the casino, who is a Godfather-like character with a large magnum. After the server returns to his home after being pursued by the casino henchmen, he teams up with his friend, an unnamed vigilante with excellent window-entering skills. Our heroes now go on the offense and get into in with the casino henchmen. He knocks one unconscious in an epic stealth scene, and kills another in a short but well-done gunfight. He gets hit and is cornered by the casino boss, but eventually has the last laugh by shooting a helium tank which blows the entire home up (see: gas leak). The whereabouts of the hero are unknown, but rumors point to a possible sequel which could feature the same character as the hero.
