orologio en Altadefinizione. Three musicians form a band. But they're not just any musicians: each has a disability that makes them particularly unsuitable for their instrument. The guitarist is deaf, the singer is tone deaf, and the bassist has a stiff arm. They lack a drummer, and to respect the group's uniqueness, they turn to a famous writer who has never played the drums. He accepts, but begins a manipulation that will wreak further havoc on the already largely dysfunctional band.
