We derive abundance ratios for nine stars in the relatively high-metallicitybulge globular cluster NGC 6380. We find a mean cluster metallicity between[Fe/H]$= -0.80$ and $-0.73$, with no clear evidence for a variation in ironabundances beyond the observational errors. Stars with strongly enhanced in[N/Fe] abundance ratios populate the cluster, and are anti-correlated with[C/Fe], trends that are considered a signal of the multiple-populationphenomenon in this cluster. We detect an apparent intrinsic star-to-star spread($\gtrsim 0.27$ dex) in the slow neutron-capture process element (s-element) CeII. Moreover, the [Ce/Fe] abundance ratio exhibits a likely correlation with[N/Fe], and a somewhat weaker correlation with [Al/Fe]. If confirmed, NGC 6380could be the first high-metallicity globular cluster where a N-Ce correlationis detected. Furthermore, this correlation suggests that Ce may also be anelement involved in the multiple-population phenomenon. Currently, a consensusinterpretation for the origin of the this apparent N-Ce correlation inhigh-metallicity clusters is lacking. We tentatively suggest that it could bereproduced by different channels - low-mass asymptotic giant-branch stars inthe high-metallicity regime or fast-rotating massive stars ("spinstars"), dueto the rotational mixing. It may also be the cumulative effect of severalpollution events including the occurrence of peculiar stars. Our findingsshould guide stellar nucleosynthesis models, in order to understand the reasonsfor its apparent exclusivity in relatively high-metallicity globular clusters.
