"Bloodline" follows documentary filmmaker, Bruce Burgess, into the so-called "bloodline conspiracy" that claims Jesus Christ married Mary Magdalene, who escaped to the south of France following his crucifixion, with their child. Over three years in the making, "Bloodline" is the first investigation to uncover new evidence: a buried wooden chest with artifacts that date to first century Jerusalem and a tomb with a mummified corpse draped in a shroud bearing a red cross.
