Suffering from insomnia, disturbed loner Travis Bickle (Robert De Niro) takes a job as a New York City cabbie, haunting the streets nightly, growing increasingly detached from reality as he dreams of cleaning up the filthy city. When Travis meets pretty campaign worker Betsy (Cybill Shepherd), he becomes obsessed with the idea of saving the world, first plotting to assassinate a presidential candidate, then directing his attentions toward rescuing 12-year-old prostitute Iris (Jodie Foster).

In early-1970s Las Vegas, low-level mobster Sam "Ace" Rothstein (Robert De Niro) gets tapped by his bosses to head the Tangiers Casino. At first, he's a great success in the job, but over the years, problems with his loose-cannon enforcer Nicky Santoro (Joe Pesci), his ex-hustler wife Ginger (Sharon Stone), her con-artist ex Lester Diamond (James Woods) and a handful of corrupt politicians put Sam in ever-increasing danger. Martin Scorsese directs this adaptation of Nicholas Pileggi's book.

Young Henry Hill (Ray Liotta), with his friends Jimmy (Robert De Niro) and Tommy (Joe Pesci), grows up in the mob and works very hard to advance himself through the ranks. He enjoys his life of money and luxury, but is oblivious to the horror that he causes. A drug addiction and a few mistakes ultimately unravel his climb to the top. Based on the book "Wiseguy" by Nicholas Pileggi.
