Blood ties and past lies prove a fatal mix when Pythagoras’s brother joins the gang to escort a precious cargo across the desert.
The boys gain an unexpected addition to their workforce with the arrival of Pythagoras’s feisty younger brother, Arcas (Will Merrick).
Charged with escorting a valuable cargo across the desert, the gang travels into the unknown with a ramshackle caravan of strangers. It isn’t long before their journey takes a decidedly spooky turn; after spending a night in a temple dedicated to The Furies, it soon becomes clear that one among their number has something to hide.
As danger closes in and a dark secret is exposed, our heroes are forced to confront some uncomfortable truths as they fight for their lives under the desert sun.
Atlantis airs on BBC One on Saturday, 16 November at 8.00pm to 8.50pm.
