Glowing softly in the West Texas desert night, artist Guadalupe Maravilla’s “Mariposa Relámpago” was once an ordinary school bus, but is now a richly decorated, mobile site for remembrance and healing.

This short documentary interweaves the bus’s journey and the artist’s journey to the United States as an unaccompanied, undocumented minor fleeing civil war in El Salvador in the 1980s into a poetic reflection of trauma, memories, and healing.
