  Magnetic flux ropes are a key component of coronal mass ejections, forming
the core of these eruptive phenomena. However, determining whether a flux rope
is present prior to eruption onset and, if so, the rope's handedness and the
number of turns that any helical field lines make is difficult without magnetic
field modelling or in-situ detection of the flux rope. We present two distinct
observations of plasma flows along a filament channel on 4 and 5 September 2022
made using the \textit{Solar Orbiter} spacecraft. Each plasma flow exhibited
helical motions in a right-handed sense as the plasma moved from the source
active region across the solar disk to the quiet Sun, suggesting that the
magnetic configuration of the filament channel contains a flux rope with
positive chirality and at least one turn. The length and velocity of the plasma
flow increased from the first to the second observation, suggesting evolution
of the flux rope, with the flux rope subsequently erupting within $\sim$5~hours
of 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 consistent
with the flux rope erupting from underneath the heliospheric current sheet, the
\textit{in-situ} measurements support the inference of a right-handed flux rope
from remote-sensing observations. These observations provide a unique insight
into the eruption and evolution of a magnetic flux rope near the Sun.
