Mark your calendars, Scorpions fans: A documentary dedicated to the band is coming to theaters with a special one-day engagement this fall.

Titled Forever and a Day, the film was helmed by director Katja von Garnier, who was granted access to the group's inner circle for 18 months while they embarked on their Final Sting tour in 2012. At the time, those dates were being billed as the Scorpions' farewell, but as the shows wore on, the band members started rethinking their decision — a change of heart that was captured by von Garnier's cameras, as depicted in the trailer above.

The end result offers what a press release describes as "a moving portrait of their unique history, packed with candid moments and Scorpions’ memories, culminating with the decision to scrap their retirement plans" — and one that has the group's stamp of approval. As singer Klaus Meine puts it, "I think it'll be a really special film for our fans."

Presented by SpectiCast and Tempest Films, Forever and a Day is scheduled to arrive in select U.S. theaters on Oct. 14. For more information and to determine local screening times near you, visit the film's official site.

Forever and a Day arrives during a flurry of activity surrounding Scorpions' 50th anniversary, including a series of deluxe reissues and the U.S. release of their latest album, Return to Forever. The band is also back on the road, where they're currently in the midst of a North American tour that's currently scheduled to run through early October; European dates are slated for later this fall and early next year.
