In a house in the South Korean capital, two former spies are still loyal to their homeland despite being trapped in exile.
Kim Young-sik and Park Hee-sung are among two dozen former North Korean agents held in the South.
Seventy-eight-year-old Park has been here for nearly half a century, but his beliefs haven't changed.
Park was captured in the 60s and jailed until his release in 1988.
As relations thawed, some North Korean prisoners were sent home. But a transfer for Park has never happened.
Every Thursday in Seoul, Park and Kim join a protest against the law which is used to imprison them.
Tension on the Korean peninsular has risen in recent weeks, but the former spies insist their homeland is no menace to world peace.
