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)
I'm not sure what to think of this episode. The interweaving of the plotline with TNG's Lower Decks eponymous episode feels off and some of the plot beats generally too contrived but not so much that I can point to something and say "this is bad."
I might need to simmer on it for a bit, or see how the second part goes.
