Ym 1977 yng Nghymoedd Cymru, mae'r ferch ysgol Siwan wedi'i obsesiwn â Shakespeare. Mae hi'n credu mai ei thynged yw bod y fenyw gyntaf i chwarae rhan Hamlet, er gwaethaf methu â chystadlu â Rhydian yng nghynhyrchiad yr ysgol. Pan mae hi'n darganfod bod ei heilun, yr actor Shakespeare enwog Richard Burton, ar fin ymweld â'i hysgol, mae hi'n benderfynol o'i wneud argraff a manteisio ar ei chyfle i gael ei chymryd o ddifrif fel actor - ond nid yw'r siawns o'i blaid.
In 1977 in the Welsh Valleys, schoolgirl Siwan is obsessed with Shakespeare. She believes it's her destiny to be the first woman to play Hamlet, despite missing out to rival Rhydian in the school production. When she finds out her idol, famed Shakespearean actor Richard Burton, is due to make a visit to her school, she is determined to impress him and seize her chance to be taken seriously as an actor - but the odds are not in her favour.
