21 (2008) follows Ben Campbell, a brilliant M.I.T. student from a humble background, who yearns for a Harvard medical scholarship but faces a $300,000 tuition barrier. Introduced to an elite blackjack-counting club by his unconventional professor, Ben joins four others—Jill, Choi, Kianna, and Fisher—under the tutelage of Professor Rosa, learning skills to exploit casino games for financial gain.
