When deceased loved ones begin to reappear, the people in Arcadia change forever.

Bellamy wants to have Jacob's tomb exhumed; Pastor Tom reaches out to a childhood friend; Caleb claims he can't remember his death.

Exhuming Jacob's grave deepens the mystery of his return; Henry struggles to accept that Jacob is really the son he lost; Maggie and Bellamy wonder if the local river holds a clue that could connect Caleb's and Jacob's deaths.

Bellamy and Sheriff Fred try to find Caleb; Maggie gives Jacob a checkup; Pastor Tom's old love returns.

Maggie turns to a person from the past for answers about the mystery; Rachael's secret ends up in the wrong hands; Bellamy and Pastor Tom try to reassure residents.

Bellamy looks for help from a surprising source. Another disappearance results in a quest for answers.

Rachael refuses to accept any treatment for the virus as she is concerned for the safety of her unborn child. Elaine's brother Ray comes down with the disease.

Anti-Returned rhetoric increases with Pastor Tom's church becoming a refuge.

The death a beloved member of the community leaves Arcadians in mourning whilst a cure for the virus is provided by stem cells from Rachael's baby.
