A Martin Lawrence (and screenwriter Darryl Quarles) comedy double bill. In 'Black Knight' Lawrence stars as Walker, an employee at a medieval-themed mini-golf-park. The morning after a blow on the head, Walker wakes up to find that he has been transported back in time to England in the 14th century. He soon finds himself allied with a has-been knight and a peasant girl in a fight against the evil King Leo and his henchman Sir Knolte. As one would expect, comic adventures ensue. Whilst in 'Big Momma's House' FBI Agent Malcolm Turner (Lawrence) is sent undercover to protect a vital witness and her son. When a notorious bank robber escapes from prison, Turner heads for the house of key witness Big Momma, where he believes the robber is heading. But Big Momma has gone away and so Turner decides to impersonate the old lady in order to trick the robber. However, when he meets and falls for the con's ex-girlfriend, things get far more complicated than he ever imagined.
