Mladi levi, ex-Yugoslav musicians, were most active in the 60’s and 70’s, when they were selling out big concert halls performing music coming from the West using instruments, which had to be smuggled behind the Iron curtain. After four decades they decided to make a comeback. The film takes us through several months long rehearsal process and brings us back to the time of their youth when music formed real friendship that at the end made them accomplish what some considered impossible. Music documentary Mladi levi: polnost časa (The Young Lions: Fullness of Time) is not just a historical document and an hommage to this legendary band but also a story about how love of music and real friendship overcome time.
