when power hungry aliens close in on earth, one of the worlds most skilled gamers must play a game of five card poker with them in order to save humanity

When power hungry aliens prepare to invade earth, one of the worlds "best card players" must play a game of poker with them, fair or otherwise to save humanity

This one is my favorite!
