'The Sea Inside' is the real life story of Spaniard Ramon Sampedro (played by Bardem), who fought a 30-year campaign in favor of his right to die with dignity. Two women try to change his life - Julia (Belen Rueda) is a lawyer who supports his cause, and Rosa (Lola Dueqas) is a neighbor who wants to convince him that life is worth living. The two women's encounters with the charismatic Ramon lead to change in their own lives.
