While embracing model escort is in danger (2,5)
I believe the answer is:
'in danger' is the definition.
'while embracing model escort' is the wordplay.
'while' becomes 'as'.
'embracing' means one lot of letters goes inside another.
'model' becomes 't' (Ford Model T car).
'escort' becomes 'take' (both can mean to guide or accompany someone).
'as' placed around 't' is 'ats'.
'is' acts as a link.
(Other definitions for at stake that I've seen before include "Being risked, like money with bookie" , "where many martyrs died" , "To be won or lost" , "Being risked, depending on outcome of event" , "In danger; at issue" .)
