According to Wikipedia a glee club is a musical group, historically of men but also of just women or mixed voices, which traditionally specializes in the singing of short songs — glees — by trios or quartets.
A young Spanish teacher really burns for the glee club. He stops at nothing to get it running even planting pot and blackmailing his pupils to join. He is not a bad guy. Quite the contrary.
He has some problems with his shopaholic wife at the same time.
There is also a hot female teacher in the mix that really roots for him. I see drama in the future…
It’s lighthearted and full of energy, hope they don’t get bogged down in drama.
But remember Glee is also malicious satisfaction (Gloat) which I am sure isn’t unintended by the writers.
