He escaped from one of the world's most brutal regimes.

Then, he decided to tunnel back in.

In the summer of 1962, a young student named Joachim Rudolph dug a tunnel under the Berlin Wall. Waiting on the other side in East Berlin were dozens of men, women, and children - all willing to risk everything to escape.

From the award-winning creator of the acclaimed BBC Radio 4 podcast, Tunnel 29 is the true story of this most remarkable Cold War rescue mission. Drawing on interviews with the survivors and Stasi files, Helena Merriman brilliantly reveals the stranger-than-fiction story of the ingenious group of student-diggers, the glamorous red-haired messenger, the Stasi spy who threatened the whole enterprise, and the love story that became its surprising epilogue.

Tunnel 29 was also the first made-for-TV event of its kind; it was funded by NBC, who wanted to film an escape in real time. Their documentary - which was nearly blocked from airing by the Kennedy administration, which wanted to control the media during the Cold War - revolutionized TV journalism.

Ultimately, Tunnel 29 is a success story about freedom: the valiant citizens risking everything to win it back, and the larger world rooting for them to triumph.
