Seeking activity in clubs, Iron Man maybe involved in accident (9,4)

'involved in accident' is the definition.
The definition suggests a singular noun which matches the answer.

'seeking activity in clubs iron man' is the wordplay.
I cannot quite see how this works, but
'activity' could be 'hunt' (hunt is a kind of activity) and 'hunt' is found within the answer.
'clubs' could be 'c' (abbreviation used in card games such as bridge) and 'c' is found within the answer.
'man' could be 'ave' and 'ave' is found in the answer.
This explanation may well be incorrect...

'maybe' is the link.
