I watched 5 to 7 again........interesting little movie
An aspiring novelist enters into a relationship with a woman, though there's just one catch: She's married, and the couple can only meet between the hours of 5 and 7 each evening.
Sidebar:The informal expression le cinq à sept refers to what could be considered a very French version of Happy Hour: the two-hour period after work, from 5 to 7 pm, when (some) people meet up with their lovers before going home to their spouses. Translation: an afternoon tryst.
