When a family employs Walter to find their missing father and husband, the only help they can offer is a partial voicemail recording of his last message to them. Meanwhile, an attractive FBI agent is also looking for the same man, and she tries to get as much information about him from Walter as she can. Also, Leo's memories of his deceased wife and daughter bring new meaning to the case and the family they're trying to reunite.

Xavier Obispo, a mob boss in Miami, asks Walter to find a voodoo doll he is convinced was created to be used against him. Willa and Walter, a non-believer in witchcraft, visit a witch who is annoyed by the fact that Walter does not take her art seriously, but decides to help them find the person that could have created the doll, leading them to a surprising participant in the mob boss' situation. Meanwhile, Isabel and Miami Det. Curtis Gillespie risk their lives while investigating a gang fight at a funeral linked to Xavier.
