Youth career Born in
Leicester, Plumptre grew up and attended primary school in
Melton Mowbray.
Notts County Plumptre joined
WSL 1 side
Notts County in 2014. She made her senior debut on 24 August 2014, as a 57th minute substitute for
Caitlin Friend in a 1–0 defeat to Liverpool. In doing so she became the youngest Notts County debutant at 16 years 108 days. Four days later she appeared as a substitute at the start of extra-time during a
League Cup semi-final defeat to
Arsenal. On 1 August 2015, Plumptre was an unused substitute for the
2015 FA Women's Cup final, the first to be played at
Wembley Stadium. She scored her first and only goal for Notts County on 30 August 2015 in a 5–0
League Cup group stage victory at home to second-tier
Yeovil Town. Notts County also reached the League Cup final in 2015, losing to
Arsenal 3–0 with Plumptre an unused substitute for the second consecutive cup final.
USC Trojans In 2016, Plumptre moved to the United States to play
college soccer at the
University of Southern California. As a freshman she made 17 substitute appearances as a
midfielder for the
USC Trojans including in every round of the NCAA postseason. She played 27 minutes of the
College Cup final as USC beat
West Virginia 3–1 to claim the second national championship in program history. She scored her first collegiate goal on 22 October 2017, the game winner in a 2–1 victory over
Washington State. After only two starts in another 17 appearances as a sophomore, she became a starter as a junior in 2018, starting in 19 of 20 appearances. In 2019, Plumptre transitioned to playing
centre-back and started all 23 of USC's games during the season that included a postseason run to the
NCAA Tournament quarter-finals. Her performances were recognised individually with All-Pacific first team and All-Pac-12 second team honours in 2019.
LA Galaxy OC In March 2019, Plumptre signed to play in the
UWS with
LA Galaxy OC during the college offseason. The team finished second in the West Conference behind
Calgary Foothills during the regular season before winning the
Championship final against the same opposition.
Leicester City In December 2019, Plumptre elected to forgo the
2020 NWSL College Draft coming out of college despite projecting as a late-first round or early-second round pick and instead returned to England, rejoining hometown club
Leicester City in the
FA Women's Championship. The Foxes had reportedly also beaten
FA WSL competition to her signature. She made her senior Leicester City debut on 19 January 2020, registering an assist on an
Ella Rutherford goal in a 3–1 win over
Crystal Palace. Plumptre's debut season with Leicester was limited to three league appearances as the season was curtailed as a result of the
coronavirus pandemic. Leicester were awarded sixth-place on a points-per-game basis. Ahead of the
2020–21 season, Leicester City Women were taken over by
King Power having previously been an independent club with a formal affiliation to the Foxes. The club became fully professional for the first time in the process. On 4 April 2021, Leicester City clinched the league title with a 2–0 win over
London City Lionesses, their twelfth consecutive league victory dating back to 4–1 defeat at the hands of the same opposition on 1 November 2020. The result earned Leicester their first ever promotion to the top-flight
FA WSL. Despite a significant summer recruitment drive to attract WSL talent in the team's bid for promotion, Plumptre remained a key figure and played in all but one game during the title win as well as all four
League Cup games as Leicester reached the knockout stage for the first time before defeat in the semi-finals. Plumptre left Leicester City following the expiration of her contract in July 2023.
Al-Ittihad On 13 September 2023, Plumptre signed for
Saudi Premier League club
Al-Ittihad. ==International career==
