A young woman gets drawn into a supernatural system working with undercover Bible characters to help people today. For her first case, the Program pairs her with Courier Aaron (Moses' brother) to help a son reconcile with his dying father before it's too late.

McKenna teams with Samuel to encourage an over-protective mother to let her adult son with Down Syndrome reintegrate into society. The case introduces McKenna to a kind (and handsome) 9-1-1 operator who receives calls from the woman's son when all he wants is a friend.

When the Program sends Abraham's wife Sarah to help an infertile couple, McKenna and Sarah get unexpected guidance from Miriam as to the kind of help they're meant to offer.

When a talented singer-songwriter resorts to self-harm, McKenna sets Rahab up as a guidance counselor at the young woman's school to unearth the root of the problem.

McKenna aids Courier Jacob in helping a drug addled reporter who lands on the streets after selling out her sister for a fix. Meanwhile, McKenna's father fights his own substance abuse demons, trying to cope with the loss of his wife.

As much as McKenna pleads for the Program to help her father, McKenna is stunned when a very special Courier is been appointed to help her instead. Before McKenna can move forward with life, she must face the part she played in her mother's tragic death.
