Checking out a ghost town a possible investment for father Victor Bennett, Phoebe is seized by visions from one of two resident ghosts, whose intense shared pain may emotionally wreck her. It's mestizo (Indian half-blood) Bo Lightfeather, who was shot and publicly flogged to death as an example for the coward town-folk by local bully rancher Sutter, which started a time loop in the mid-1800s. Despite Prue's reservations, the only way to help Phoebe, as Leo is powerless in the present, is for Cole, who has demonic experience in traveling time and space, to take her sisters back and break the loop, by altering Bo's fate.
