Should I know who that... entity... is?
Indiana Jones's ex-girlfriend runs a dive bar in Mongolia or something; she has a medallion the Nazis are seeking, because (many details omitted) it can help them locate the Ark of the Covenant.
The bad guy is trashing her bar looking for the medallion when Indiana Jones shows up to save the day.
The place catches fire and the medallion, next to the flames, gets ...not red hot, but too hot to touch.
The villain grabs it and suffers 3rd degree burns on his hand, which are an imprint of the marks on the medallion.
Later he gives the Nazi salute and you see the marks on his hand.
This is a take off of that, with the imprint of the gear instructions on the manual transmission handle for a stick-shift car...
