In Mr. Sunshine, Ben Donovan is a self-involved manager of a San Diego sports arena, the Sunshine Center, where curious mishaps and bizarre requests are nothing more than ordinary. Working alongside him is his boss and arena owner Crystal attractive, powerful and highly erratic; Alice the cute, tomboyish marketing director and Ben's friend with benefits; Alonzo a former basketball player, handsome and unbelievably happy; Ben's assistant, Heather, pretty, sweet, but terrifying because she once lit a boyfriend on fire; and Crystal's son, Roman, sweet-faced, clueless and Ben's newest employee.
