Logline
Who knows? They never released one.
Edit: They finally released one - how novel to release the actual episode first!
Captain Freeman assigns the Lower Deckers an overly safe mission to try and keep a self-destructive Mariner out of danger.
Written by: It's a secret (it was Mike McMahan)
Directed by: We're not tellin' (it was Brandon Williams)
