A Manhattan scientist races against time to find a cure for a devastating viral outbreak in the science fiction thriller "I Am Legend." The film, which airs at 10:40 p.m. on BBC Three, stars Will Smith and Alice Braga.

Set in a near-future New York City, the story follows a pandemic that wipes out 90% of the global population. Those infected are transformed into aggressive, vampire-like beings. Smith’s character is a military scientist who appears to be the sole survivor immune to the virus. By day, he navigates the deserted urban landscape while avoiding the infected, and by night, he continues his efforts to develop a cure.

The movie is adapted from the 1954 novel of the same name and explores themes of isolation, survival, and the search for hope amid widespread devastation.
