  We have observed the hot post-AGB star ZNG 1 in the globular cluster M5 with
the Far Ultraviolet Spectroscopic Explorer (FUSE). From the resulting spectrum,
we derive an effective temperature T_eff ~ 45,000 K, a rotational velocity
v_rot ~ 100 km/s, carbon and nitrogen abundances approximately ten times solar,
a wind with terminal velocity near 1000 km/s, and evidence for an expanding
shell of material around the star. The carbon and nitrogen enhancements suggest
dredge-up of nuclear-processed material on the AGB. The high rotational
velocity may reflect a previous merger with a binary companion.
