The emotive, visually poetic "Sunshine" explores society's shifting view of unwed mothers within the lifetime of filmmaker Karen Skloss, who was given up for adoption in 1975 by an unmarried woman and who became a single mom herself in the late 1990s. The film compares her story with that of her birth mother, who checked into a home for unwed pregnant women, and also examines the meaning of family. Her biological mom and grandfather, adoptive parents and her child's father participate.
