The first episode in which Charlie - a baseball player with anger issues turned anger management therapist - decides to return to therapy after a bad run-in with his ex-wife's new boyfriend. The only problem is he just happens to be sleeping with the one therapist he trusts: his best friend, Kate.

Charlie challenges his group to do thirty-six hours of sleep deprivation therapy so that their "inhibitions come down and the truth comes out" - except the result turns out to be the exact opposite.
