Nickelodeon stars Jennette McCurdy and Ariana Grande team up in Sam & Cat, a spin-off of iCarly and Victorious that follows the continuing story of two of the shows' most beloved characters. The story opens with a chance encounter between Sam Puckett (McCurdy) and Cat Valentine (Grande) that evolves into an unexpected friendship. With Cat on the lookout for a new roommate since her grandmother, Nona (Maree Cheatham), took refuge at the local senior community, and Sam drifting after her best friend left their web show to move to Italy, the two wind up living together and running a babysitting service for neighborhood kids. They're often joined in their adventures by Dice (Cameron Ocasio), the apartment complex's well-connected go-to guy.
