Magnetic flux ropes are a key component of coronal mass ejections, formingthe core of these eruptive phenomena. However, determining whether a flux ropeis present prior to eruption onset and, if so, the rope's handedness and thenumber of turns that any helical field lines make is difficult without magneticfield modelling or in-situ detection of the flux rope. We present two distinctobservations of plasma flows along a filament channel on 4 and 5 September 2022made using the \textit{Solar Orbiter} spacecraft. Each plasma flow exhibitedhelical motions in a right-handed sense as the plasma moved from the sourceactive region across the solar disk to the quiet Sun, suggesting that themagnetic configuration of the filament channel contains a flux rope withpositive chirality and at least one turn. The length and velocity of the plasmaflow increased from the first to the second observation, suggesting evolutionof the flux rope, with the flux rope subsequently erupting within $\sim$5~hoursof the second plasma flow. The erupting flux rope then passed over the\textit{Parker Solar Probe} spacecraft during its Encounter 13, enabling\textit{in-situ} diagnostics of the structure. Although complex and consistentwith the flux rope erupting from underneath the heliospheric current sheet, the\textit{in-situ} measurements support the inference of a right-handed flux ropefrom remote-sensing observations. These observations provide a unique insightinto the eruption and evolution of a magnetic flux rope near the Sun.
