ALTERNATIVE VALENTINE

In a salute to that old standard, the May-December romance, Lifetime will present the broadcast premiere of “P.S.,” a story about a lonely admissions director (played by Oscar nominee Laura Linney) and the relationship that develops between her and a college applicant (played by Topher Grace), who happens to share the same name as her dead high school sweetheart.

(Lifetime, Thu., 9 p.m.)
