A fairly amateurish movie about a Math professor who is an expert card-counter and ipso facto, banned from most casinos. So he trains 3 math graduates to count cards and work as a team to fleece casinos in Blackjack.

The utility of a simple mapping function which maps all 13 card values on to a card-counting set {-1, 0, +1} is nicely, if all too briefly, explained. There are 2 or 3 very contrived situations which show the 3 students to be math savants (the stereotypical Chinese who memorizes pi, the eastern european girl who talks about 90-degree rotations while serving pizza, etc). Not terribly entertaining.
