exec means you will never reach the next line. There is a declarative
way to change dirs, so you don't need the script stanza at all:

---
respawn
chdir /path/to/plugin_installation
exec bundle exec ./bin/newrelic_rs
---

Note that if you want it to start at boot, don't use any of the weird
compound start ons you see:

start on runlevel [2345]
stop on runlevel [016]

Those two should be fine.
