Teenager Draylen Mason dreams of being a neurosurgeon, and he also excels in music, which draws an offer to study the double bass under world-renowned professors at the University of Texas. Ten days after the first bomb exploded in an Austin suburb, Draylen notices a package on the porch and brings it into his family's home. The package explodes, and it becomes clear that the death of Stephan House, a 39-year-old Black man, was not an isolated incident. Since Draylen is also Black, the community fears that Austin's Black population is being targeted by an unknown serial bomber.
