Professional tango dancer Ramona, a transsexual born Ralf Hellwig, is brought to ER badly beaten up by a masked man near the Hamburg rowing club, where he was long a member with buddy Andreas Wiegand. It's presumably a hate crime, which even macho Tariq has difficulties situating, but the victim refuses to speak up. His employer, dance school owner 'Eduardo Esteban', has his own dark secrets. Ralf's adult son Carsten Waits was completely estranged, moving to the US on school exchange from age 18 and is visiting Hamburg, now a pilot in Arizona. .
