[3] The movie stars Tijan Njie and Elan Ben Ali as the lip-synching stage artists Rob Pilatus and Fabrice Morvan respectively, as well as Matthias Schweighöfer as the instigating music producer Frank Farian.

[4] Robert "Rob" Pilatus – a mixed-race child adopted by a German couple in an all-white Munich neighbourhood – finds solace listening to Boney M., the pop group created by established music producer Frank Farian.

Rob and Fab discover the recording is a cover version but Frank and Milli assure them that re-recording original songs is common industry practice, and "Girl You Know It's True" climbs the charts across Europe.

In 1989, Rob and Fab – now known as Milli Vanilli – are signed to Arista Records in America, where they are warmly welcomed, although executives arrange for a dialect coach to help them refine their strong European accents.

Apart from a technical glitch incident that causes their backing record to skip during a show, their Club MTV tour appearances are a success, with "Baby Don't Forget My Number", "Blame It On The Rain", and "Girl I'm Gonna Miss You" hitting No.

The original session singers, Brad Howell and John Davis, however, are upset that the duo are receiving the recognition and accolades they believe are rightfully theirs, especially after Milli Vanilli are nominated for a Best New Artist Grammy, which they unexpectedly win in 1990.

Taking decisive action on his own terms, Frank holds a press conference in New York, where he publicly admits that Milli Vanilli had never sang on their album, igniting a major scandal.

While Numarx reacquire their publishing rights – now worth millions – and subsequently become successful music executives, Rob spirals deeper into addiction and Fab, unable to cope with his friend's situation, moves out of their shared apartment.

In 1998, after living a life of crime and drug addiction, Rob returns to Germany, where Frank offers to send him to rehab in Sri Lanka, but he dies of an overdose, leaving Fab devastated.
