Born in Leicester on 8 May, 1998, she scored six times in 30 appearances for the Young Lionesses, and participated in two UEFA European Women's Under-17 Championships for England.
Plumptre chose to represent Nigeria at senior international level, making her debut in their 2022 Africa Women’s Cup of Nations Play-Off against Ivory Coast in February 2022, playing 90 minutes of both legs as the Super Falcons recorded a 3-0 aggregate victory to book their place in the flagship continental competition, subsequently reaching the semi-finals.
Going back to her time in America, the defender became an NCAA national champion with the USC Trojans in 2016, and was also invited to the White House in Washington DC in January 2017 with the University of Southern California Women’s team.
After joining Leicester City's Girls' Centre of Excellence as an eight-year-old, Plumptre became a full-time professional for the Club she supports, and a valued member of the squad, playing 25 times in 2020/21 and winning Players' Player of the Season at the Club's End of Season Awards.
Composed in possession and expressive enough to often carry it into midfield, centre-back Plumptre scored her first goal for LCFC Women in a 2-1 victory over Sheffield United at Farley Way Stadium on 10 January, 2021.
After lifting the Barclays Women's Championship trophy, the Nigeria international, who has made more appearances than any other current LCFC Women player, signed a new contract in June 2021 to keep her at the Club until at least the summer of 2023.
Her first goal of 2021/22, meanwhile, arrived against Everton in the Continental Tyres League Cup on 3 November, 2021, adding her first-ever WSL strike in a 3-0 home victory over West Ham United in February 2022.
