Omission of THAT

[Xinfu]

-This is a play (I think this is wrong and THAT must be used here) comes on the wall-to-wall circuit in ten minutes.

Do you think THAT is not omissible? because THAT here is the subject of the following that-clause, unlike 'He is the man (that) I like'.

[Señor Hombre]

'That' should not be omissible in this sentence, as the grammar will not be correct.

This is a play that comes on the wall-to-wall circuit in ten minutes.

If THAT is to be left out, then you could use;
This play will come on the wall-to-wall circuit in ten minutes.
