But it's not exactly what it appears to be. Rather, for an investigation into the suicide of a retired Navy officer who left a rare, valuable (and possibly stolen) coin to the National Museum of the Navy, the team imagines themselves in his life story to piece together how he ended up with that coin.
Exec producers Frank Cardea and Steven D. Binder also tease an arc they've been building towards.
