In the gritty housing estates of Glasgow, Mungo and James are expected to be enemies—Mungo a Protestant, James a Catholic. But amidst the sectarian divide, they find an unexpected sanctuary: each other.

Hidden away in the pigeon dovecote James built for his prized racing birds, they dream of a future far from the constraints of their world. Their forbidden love blooms, offering a glimmer of hope in a stark reality.

But when Mungo's mother sends him on a fishing trip to a remote loch with two mysterious men, his world shifts dangerously. Mungo must summon all his courage to find his way back. Will he return to James, or will the forces tearing them apart prevail?
